Analysing pedigrees
Comments
-
This might seem an excessive table.
These are dams born 1970+ who have produced the winners of ten or more Group or Graded races.
The reason I'm showing the detailed list is it gives clues to the source of quality in horses.
I think it is instructive to examine the pedigrees of these dams (not the pedigree of their group winners). I think you will find clues to the source of quality.
Some dams produced Group winners to only one sire, other to many different sires, and some to similar sires (same sire line).
I could go through the pedigrees one at a time but the explanations would fill many pages. I'm listing these to indicate that good horses are not produced by chance ("breed the best to the best").
It might be- where a dam produced Group winners to only one sire then it is the pedigree of the Group winner that is important (not so much the sire and dam);
- where a dam produced Group winners to many different sires then there might be something in the pedigree of that dam that is important
- where the dam produced winners to similar sires that is a bit like producing winners to one sire (the pedigree of the group winner is important).

In the list above you can see that the mare Castle Moon, rated 79, had three Group race winners: Moon Madness; Sheriff's Star; Lucky Moon.
I think Moon Madness, St Leger winner, was bred by Lavinia, Duchess Of Norfolk, and she was racing on a small budget. Afaik that is why she chose Vitiges, an inexpensive stallion.
You will see that she started out well, and despite success, she moved on to other stallions probably at a greater cost. Why change a winning formula?
If anyone has the time they should examine the pedigrees of these horses.
Moon Madness had:
Prince Bio (sire) duplicated in his 4th generation, producing a son and daughter.
Palestine (sire) twice in his 4th and 5th generation producing a son and daughter.
Hyperion (sire) in his 5th generation three times producing a daughter, son, and daughter.
Pharos (sire) in his 6th generation twice, producing a son and daughter.
There are a few more half siblings in his pedigree.
He was Castle Moon's best offspring.

“The Duchess owns a stud, which is managed by Dunlop, yet another strin to his bow. Most people would have found trainin 200 racehorses enough, but he likes to be involved with such things as the European Pattern Race Committee, a Jockey Club involved in research into the virus, and running the stud as well. The Duchess bought a share in a stallion called Vitiges, who turned out to be such a disaster that people wouldn’t send him the mares to submit to his embraces. He ended up being packed off to Japan, to stand at stud there.
The Duchess said “I had a mare called Castle Moon, which was quite well bred, but really rather small, and not very good either. So I put her to Vitiges – the result was Moon Madness. The mare has also given us Wood Chanter, who is a full brother to Moon Madness, and quite promising, and Sheriff’s Star, a good horse by Posse – and Posse was a failure at stud, So it is not the sire I have to thank, but the mare. She has a two-year-old in training by Mummy’s Pet called Moon Mystery, and a yearling by Touching Wood, and she is in foal again.”

Equinome have a gene speed test at €590 a horse.
Equinome have an Elite Performance Test at €1,450 a horse.
would each foal not be genomically tested before sale?
I don't know. Perhaps some horses are tested before sale but I do not know if the results must be revealed. They might be entered in a sale if they are tested and the results are unfavourable.
is there an index at which those figures are judged on in terms of performance and heritable traits?
Equinome have results for horses they tested. It looks like customers get results for one horse, not data for their horse and all other horses tested.
There are general statistics on the Equinome site but not with horse names.
Is there not somethings similar for horses and if so how does it fit in with your figures?
That data is valuable and I have nothing. My guess is you pay for one horse information only.
Genetic testing categorises a living foal by distance suitability and quality.
I'm trying to predict quality by analysing ancestors in a pedigree, and predicting potential quality before a foal is bred, or if already bred and unraced.

SIX GENERATION INBREEDING ANALYSIS OF RATED HORSES
In February 2017 I completed work on analyzing the inbreeding in the six generation pedigrees of 159,222 rated horses.
Inbreeding is the duplication of a horse in the pedigrees, typically a sire.
In their lifetime sire can produce thousands of foals, dam produce perhaps a dozen.
In my sample of 159,222 rated horses only 3,462 did not have inbreeding in the first six generations, 97.8% had inbreeding.
In my reading about inbreeding one author says speed is not inherited from the sire or dam, but is a product of inbreeding, typically in the 4th, 5th and 6th generations.
I am sure owners of stallions would not agree with that statement.
Inbreeding might seem simple to record. See a sire twice in a pedigree, and that is inbreeding.
It is more complex.
What should also be recorded is the sex of the offspring of that sire.
In the pedigree he could have produced two sons, a son and daughter, or two daughters.
And there are 2+4+8+16+32+64=126 ancestors in a six generation pedigree. It often happens that one, two, three, four or more sires each appear twice or more times in the six generations.
That is what I did in January and February 2017.
I wrote a database programs that analysed each of 159,222 pedigrees and recorded the output in a results file.
There were 37,057 colts, 50,335 geldings, 71,830 fillies.
There average ratings were: colts 93.79; geldings 74.45; fillies 74.43.
COMPARING COLTS RESULTS WITH GELDINGS RESULTS
When I did the work almost two years ago the average ratings for the 37,057 colts, 93.79, were much higher than the gelding ratings, 74.45.
At the time I did not purse the matter, assuming that it might be a case where identical pedigrees, say full sibling brothers, produced horses with different abilities, and the less able runner was gelded.
I though that it was a case of the pedigree clicking, firing, sparking, due to chance, and at other times going off like a wet firework.
This morning I decided to compare the results from the colts and geldings to see if there was anything to indicate why there was a 19.34 rating difference (93.79-74.45).
areas where the 37,057 colts rated average 93.79 differ from the 50,335 geldings rated average 74.45
sire inbreeding only examined
the colts (rating avg 93.79) on average have more groups 2.811 to 2.679 (4.9%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more siblings 0.852 to 0.624 (36.6%) than the geldings (rating avg 74.45) ... I think this is siblings produced by sires and dams
the colts (rating avg 93.79) have more male offspring 7.111 to 6.955 (2.2%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have many more female offspring 5.237 to 4.439 (18.0%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_mf 0.816 to 0.754 (8.2%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_mmff 0.370 to 0.323 (14.5%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have less s_mm 0.738 to 0.792 (-6.9%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have less s_mmmm 0.257 to 0.288 (-10.5%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_ff 0.415 to 0.363 (14.4%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_ffff 0.057 to 0.040 (43.4%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_one 3.546 to 3.134 (13.2%) than the geldings (rating avg 74.45)
the colts (rating avg 93.79) have more s_sibl 0.797 to 0.568 (40.3%) than the geldings (rating avg 74.45) ... I think this is siblings produced by sires
Notes:
groups: two or more of a duplicated sire is one group; two groups would be two different sires duplicated
e.g. Rainbow Quest (1981) rated 133, has four duplicated sire groups:
Nearco, producing two sons; Blandford, producing three sons and one daughter; Phalaris, producing a son and daughter; Teddy, producing two sons and a daughter
s_mf ... a sire group producing a son (m) and daughter (f)
s_mmff ... a sire group producing more than one son (m) and daughter (f) e.g two sons and one daughter.
The most common inbreeding you see is two or more sons of a sire, typically Northern Dancer or Danzig.
I have always though this a negative in pedigrees, and the numbers support this opinion.
The differences appear small, but expressed as percentage seem larger, and the rating difference of 19.34 is large.0 -
For a while I have not been satisfied with the pedigree analysis results I got in Jan/Feb 2017 with the average ratings for
(1) 18 different inbreeding types in a six generation pedigree (126 ancestors 2,4,8,16,32,64)
(2) the number of occurrences of the 18 inbreeding types
Immediately whoever is reading this thread can not understand what I am saying.
(1) different inbreeding types could be:
A sire appearing twice in a six generation pedigree producing a son and daughter.
I call this s_mf (i.e. sire producing male and female).
There could be s_mf; s_mm; s_ff, and the same for dams; d_mf; d_mm; d_ff, and many other types for three or more duplicated sires, full siblings ...
(2) the number of occurrences
Example: Northern Dancer twice, Native Dancer twice; Alycidon twice, all producing one son and one daughter, would be 3 occurrences of s_mf.
This is from the Jan/Feb 2017 results.
type occ s_mf count
colts 0 93.11 15847
colts 1 93.81 14034
colts 2 94.79 5621
colts 3 96.71 1300
colts 4 96.65 229
colts 5 107.57 23
colts 6 91.00 3
You can see that for each increase in number of occurrences of s_mf there is a rating increase for those colts (on average).
The problem with these averages is: the 15,847 colts averaging 93.11 rating also have in their pedigrees many other different inbreeding duplication types from the other 17 inbreeding types
e.g. two sons of a dam duplicated twice; three sons and two daughters of a sire duplicated five times.
The 15,847 colts above averaging 93.11 also had in those 15,847 six generation pedigrees these (I'm only showing 2 of the 17 other inbreeding types below)
type occ s_mm s_ff
colts 0 5981 10401
colts 1 6800 4324
colts 2 2588 994
colts 3 450 121
colts 4 28 6
colts 5 0 1
Explanation:
2,588 colts had 0 x s_mf and 2 x s_mm
4,324 colts had 0 x s_mf and 1 x s_ff
Removing those from the average rating calculation (previously 93.11 or more accurately 93.109926) I got a revised average of 92.42 (92.434242).
(the only reason for six places of decimals is just to help with program verification).
My methodology removing the effect of the other inbreeding may not be correct.
REVISED RATINGS
This shows the original and revised for s_mf
You can see the difference that getting rid / adjusting for the other inbreeding makes.
It is more obvious how sons and daughters of a duplicated sire are better than two sons of a duplicated sire (yet to be calculated/proved).
I think revising the s_mm will show figures lower than these below.
type occ s_mm count
colts 0 93.55 16074
colts 1 93.97 15396
colts 2 93.97 4857
colts 3 93.93 688
colts 4 92.50 42
Now all I need to do is the same "rating revision" program for another 27 occurrences x 17 other inbreeding types, 27 x 17 = 459.
The average for all the 37,057 colts is 93.7780.
I'll have a think about doing a second iteration of the ratings revision.
That might further differentiate the good inbreeding from the bad (increase the ratings differences).
My plan is to produce a formula that might approximate a horse rating just from the pedigree inbreeding.
In November 2018 I rewrote the pedigree analysis program but that is unfinished.
Using runner ratings may not have been a good idea.
It might be better to use the difference between the runner rating and the rating of its dam who produced the runner.
i.e. how much did the pedigree improve the runner (or impair it).
s_mf s_mf
type occ original revised
colts 0 93.11 92.44
colts 1 93.81 93.83
colts 2 94.79 95.77
colts 3 96.71 99.62
colts 4 96.65 99.53

If you are thinking of buying a broodmare for the flat I think it is a good idea to look at the sires of the females in her pedigree.
This is imo the weakest part of many broodmares, a selection of sires in her pedigree who are rarities in the breed.
These rarities are seldom found in the pedigrees of stallions at stud, and you can not get inbreeding (and imo speed/class) without duplications (a bit like hand clapping with one hand).
Gen 1 Gen 2 Gen 3 Gen 4 Gen 5 5 Gens
ancestors 2 4 8 16 32 62
male 1 2 4 8 16 31
male -> female 0 1 2 4 8 15
my mare 1 0 0 0 4 5 9
my mare 2 0 0 1 4 8 13
The above table shows there are 62 ancestors in the first five generations of a mare's pedigree.
If you take the five generation pedigree of a sire and put it with the five generation pedigree of a mare you get the six generation pedigree of their foal (2+4+8+16+32+64 = 126 ancestors).
There are 62 ancestors in 5 generations, and 31 of those are male.
These 31 male ancestors produce 15 males, 15 females, 1 unknown sex (the foal).
I think you should buy a mare with as many of the 166 sires listed below as possible in her first 5 generations i.e. a number close to 15.
I ran off a list from my data of 166 sires born before 1990 who produced over 1,000 in two generations (i.e. grandsons and granddaughters).
The number 1,000 is an arbitrary cut-off point, but indicates sires who produced sons and daughters who went on to produce sires.
I tested the idea with my two mares.
You can see that the second mare, bought in December 2018 at Newmarket, has almost the complete set with 13/15.
She has in her first five generations daughters of Buckpasser, Damascus, Danzig, Graustark, Herbager, In Reality, Nashua, Nearctic, Northern Dancer, Prince John, Rainbow Quest, Sir Ivor, Tom Fool.
It is a bit difficult to get sires of females in the first generations (Gen 2, Gen 3) from the list of 166 sires below as they probably are not long at stud
(i.e. they were born after 1990, my cut-off point) and have not yet got 1,000+ second generation offspring).

The great mares of the modern era not only produce multiple top-class racehorses; the very best of them will also prove adept at passing on their genes to future generations through their sire sons. Remarkably, there are three mares since pattern racing commenced that have produced five sons that have gone on to sire at least one Group 1 winner. Strange as it may sound, producing multiple Group 1 sires, while being noteworthy for the mare, may not end up being so for the breed. To construct a more meaningful ranking, our mares must have sired two or more stallion sons each responsible for at least five Group 1 winners. Influential sires are key.
The full-brothers Sadler’s Wells and the once-raced Fairy King have their dam Fairy Bridge at the top of our list. Fairy Bridge, a May foal who cost Robert Sangster only $40,000 as a yearling, went unbeaten in her only two races, both at two, earning a 115 rating from Timeform. Two other sons, Perugino and Tate Gallery, have also contributed to her tally of 91 Group 1 winners. A mere 13 Group 1 winners behind Fairy Bridge is the great Urban Sea, dam of the equally great Galileo and Sea The Stars. It’s only a matter of time–most likely sometime in 2018–that this Arc heroine takes over at the top.
The next three mares–Weekend Surprise, My Charmer and Glorious Song–all belong to eras when foal crops were much smaller. So, whilst their numbers are less impressive, their achievements are still remarkable. Weekend Surprise produced five sons that sired at least one Group 1 winner, while Glorious Song is the only mare among the group to have had three sons sire five or more winners at the top level.

Hope you don't mind me dropping this into your thread. The incredible influence that Urban Sea has brought to European racing in recent times makes me think that the damside is becoming more and more important in the production of top racehorses.
Coolmore's ability to deliver multiple Gr 1 winners from exceptional individual broodmares such as You'resothrilling makes a bit of a mockery of the overemphasis on the stallion input into top racehorses.
You'resothrilling's first 5 foals ( the 3 Gp1 winners Marvelous, Gleneagles, Happily and Gp1 placed Coolmore and Taj Mahal ) are all by Galileo who is himself out of the mighty pedigree influencing broodmare Urban Sea. There's no accident to the brilliant success of the offspring of these super producing blue hens in Urban Sea and You'resothrilling. Those two ladies have both had foaled 3 or more Gr1 winners, 4 in Urban Sea's case .
These two mares make any sire's record look slack in comparison to their own abilities to produce top class racehorses. You'resothrilling herself is a daughter of another super producer broodmare in Mariah's Storm, dam of the top class racehorse and top US stallion Giant's Causeway. That Storm Cat Mariah's Storm mating produced at least 4 top class producers, You'resothrilling, Pearling ( dam of Decorated Knight ), Giant's Causeway multiple Champion US sire and Freud a minor champion sire in New York State.0 -
.A couple of weeks ago the manager of a TrueNicks enrolled stallion called to tell us that a hypothetical mating had generated Dosage Figures that were all zeroes – zeroes for each category in the Dosage Profile; a Dosage Index of zero; and a Center of Distribution of zero.
A check confirmed that this was not an error, and nor was it the result of an obscure pedigree. The sire in question is a son of Candy Ride out of a Deputy Minister mare, and the dam is a daughter of Henny Hughes, the sire of the magnificent Beholder, and broodmare sire of Monomoy Girl, the Champion Three-Year-Old Filly elect of 2018. What, in fact, the result indicated is that Dosage itself is beginning to disappear from modern pedigrees.
http://cs.bloodhorse.com/blogs/truenicks/archive/2018/12/10/the-disappearance-of-dosage.aspx
Not quite sure what to make of that, but I do find that in US breeding the Dosage Index results make little sense in comparison to how the Dosage Index is very useful with European bred horses.0 -

Feel free to post on the thread if you like.
Many would say what I post is identical to what comes out of the back end of a horse..
Thanks for that interesting chart of dams of important sires.
One of the inbreeding groups I record in a six generation pedigree is two sons of a dam.
If a dam can produce two sons who become sires, and those sires produce enough offspring to be common in pedigrees, then you know that dam is special.
I am inclined to think Urban Sea's dam, Allegretta (1978), is another strong influence.
Her pedigree is German although trained in England by Michael Stoute, rated 101 (2yo) and 97 (3yo). Her dam won over 5f.
Timeform said “will stay 12f” but she was tailed off in the 1981 English Oaks.
I watched that race on Youtube just now and have never seen a classic field spread out as much at the finish.
Allegretta is dam of English 2000 Guineas winner King’s Best. She also bred the useful Allez Les Trois, who produced French Derby winner, Anabaa Blue.0 -

Urban Sea's German heritage is quite speedy and one that has produced bucket loads of black type producers. This may explain the ability to comfortably stretch stamina from 1m to staying distances that many of the Urban Sea line seem to possess. Interestingly ( at least I think? ) Urban Sea seems to be free of Northern Dancer influence which means that maybe the outcross she provides for the Northern Dancer line is the secret of her success as a pedigree influence.
I think that you might be interested in this article which seems to suggest that inbreeding is a bad thing. Although inbreeding to Urban Sea seems to be very successful.This morning you may see that we have extended the computations of the Coefficient of Inbreeding and Coefficient of Relatedness to 10 generations. These coefficients were previously calculated over 8 and 6 generations respectively and were done to that generation previously due to computational restrictions, i.e, the speed of the computers and the frequency of TrueNicks requests being run had an effect on report delivery time.
We have been able to extend the computation out to 10 generations thanks to the programmers at TJCIS, and it is also where a nice balance is found between the calculations of these coefficients and pedigree completeness. As we go further back into a pedigree, the completeness of the page starts to reduce as names are either founder horses, where no ancestor is known, or names where ancestry cannot be reasonably verified. This incompleteness has an effect on the calculations for inbreeding and relatedness as they then start be underestimated, especially where the incompleteness is skewed to one side of the pedigree over another.
As a reminder, we first placed these coefficients back in 2013 - you can see the blog post for that here. The coefficient of inbreeding (COI) was introduced by Sewell Wright back in 1922 to express the expected percentage of homozygosity (closeness to being identical) arising in a given mating. It can also be viewed as the average chance that any one gene pair is homozygous due to inheritance from a common ancestor. A low inbreeding coefficient means a low level of inbreeding, at least in paper terms. The vast majority of racehorses have an inbreeding coefficient of less than 5%. Inbreeding coefficients over 5% are unusual, and over 10% are very rare.
Recently a paper by Todd and colleagues pointed to higher levels of inbreeding having a negative impact on racehorse performance. Their analysis of data from 135,572 Thoroughbred horses in Australia revealed a strong negative relationship between Wright’s inbreeding coefficient and five measures of racing performance that encompass a range of factors that contribute to exercise performance. These included two measures that are based on the assumption that more successful individuals earn more prizemoney: cumulative prizemoney earnings and prizemoney earnings per start. They also included two measures of constitutional soundness: total number of race starts and career length and accounted for consistency of performance with the measure winning strike rate. The authors suggested that the negative relationship between inbreeding and performance can be explained by a genetic load of partially deleterious alleles still being carried by the population.
The Coefficient of Relatedness (COR) answers a slightly different question. The coefficient of relatedness provides a way of objectively assessing the similarity of two pedigrees by giving a number that is a direct measure of shared ancestry. In this case, the two pedigrees that we use are the sire and dam of a hypothetical or named horse mating. This figure will vary from the COI because it is possible, indeed quite frequent that a sire or dam can be inbred themselves, thus contributors to the inbreeding of their offspring, but the level of inbreeding between the sire and dam can be low. That is, one parent can be intensely inbred while the other a relative outcross. There has been no studies on the COR and its relationship to performance.
In pushing these two metrics out to 10 generations, we have also added the Pedigree Completeness to 10 generations, as well as a count of the unique ancestors in a pedigree from the first to the 10th generation. This also sets the platform for us to implement the use of the Ancestral History Coefficient, which in the paper from Todd and colleagues above, had a positive influence on racetrack performance. With this latter metric in place, it will give us the platform to develop TrueNicks 2.0, a significantly more predictive algorithm for matings, which we have in the works to develop and launch in 2019.

It might be that ancestors in the dam side of urban Sea are important to the breed in IRE & GB now.Urban Sea's German heritage is quite speedy and one that has produced bucket loads of black type producers. This may explain the ability to comfortably stretch stamina from 1m to staying distances that many of the Urban Sea line seem to possess. Interestingly ( at least I think? ) Urban Sea seems to be free of Northern Dancer influence which means that maybe the outcross she provides for the Northern Dancer line is the secret of her success as a pedigree influence.
I think that you might be interested in this article which seems to suggest that inbreeding is a bad thing. Although inbreeding to Urban Sea seems to be very successful.
I know Galtee More (1894) (twice) and Ard Patrick (1899) (six times) feature in the pedigree of Allegretta (1978), both out the mare Morganette.
Those two sires, good racers, absent from IRE & GB pedigrees for about eight generations might be the influence.
Ard Patrick won the English Derby, with Sceptre 4th.
Sceptre had earlier won the 1000 Guineas, 2000 Guineas, English Oaks.
The following year Ard Patrick beat Sceptre and that year's Derby winner Rock Sand in the Eclipse Stakes.
Galtee More won the English Triple Crown in 1897.
Morganette also produced Irish Derby winner Blairfinde.
The pedigree expert Les Brinsfield died in 2018.
He pointed out that when the mare La Troienne (1926-1954) went from France to the USA almost every horse she produced over there was successful - 14 named foals, 12 raced, 10 winners, 5 five stakes winners, 2 Hall of Fame inductees.
Brinsfield though the reason was La Troienne had a daughter, Young Giantess, of the first English Derby winner, Diomed in her pedigree.
Diomed was an unsuccessful sire in England, but when he went to the USA at 21 years of age, he was outstanding.
When many horses are successful later pedigrees become saturated with sons of that sire as everyone wants to cash in by standing sons of the successful sire.
Diomed left only sire sons in the USA. What was lacking in the ancestors in USA pedigrees from about 1870 onwards was daughters of Diomed.
Brinsfield mentioned that Young Giantess, a daughter of Diomed, was many times in La Troienne's pedigree, as well as another (unnamed) daughter of Diomed.
My version of TesioPoewer allows you list the ancestors of a horse to 12 generations. When I did that for La Troienne Young Giantess was there 57 times and the unnamed Diomed daughter 8 times.
My guess is if I ran deeper analysis (i.e. took the four grandparents of La Troienne) and did a search of each of them the number for Young Giantess would be much higher than 57.
On the question of inbreeding being good / inbreeding being bad, a poster on thoroughbredvillage.com.au ridiculed inbreeding and said DNA tests have proved errors in records therefore analysis is futile.
A few weeks later her was telling us that inbreeding to Herod was good, and linking to the research.
When researchers breed a good horse people will take notice, or they tell people how to breed a good horse ("hurlers on the ditch").0 -
I wrote programs In Jan/Feb 2017 to analyse the inbreeding in the six generations pedigrees (2+4+8+16+32+64 = 126 ancestors) in 159,222 horses (37.057 colts; 50,335 geldings; 71,830 fillies).
At that time the results were promising.
There were 18 inbreeding types identified, 9 sire inbreeding duplication types, and 9 dam inbreeding types.
Examples of three groups (inbreeding types) are a sire duplicated twice (1) producing two sons, (2) producing a son and daughter, (3) producing two daughters).
Of course most pedigrees had only one or two inbreeding types, the most common being two sons of a duplicated sire back in the fourth and/or fifth generations.
The above is only one of six pieces of analysis, one done (above), five to do.
By "done" I mean reassessed. I have the Jan/Feb 2017 average ratings for the other five.
Done: sire inbreeding in colts
Not done: dam inbreeding in colts; sire inbreeding in geldings; dam inbreeding in geldings; sire inbreeding in fillies; dam inbreeding in fillies.
Why did I concentrate on sire inbreeding in colts?
In my data the colts were rated 93.78 average; geldings 74.45; fillies about the same as geldings.
It made more sense to concentrate on the horses with ratings about 20 points above the breed average.
And sire inbreeding is more common than dam inbreeding, as sires produce hundreds or thousands of offspring in a lifetime, broodmares perhaps a dozen.
I truncated the data in the above graph, removing ratings averages where the number of colts with an inbreeding type was 40 or less.
In one graph line the data is 93.5 (34,992 colts); 99.3 (2,021 colts); 95.2 (43 colts) (beside the text box [Value "X" Axis Major Gridlines]) and not shown 41.1 (1 colt).
The 95.2 dip in the graph line is misleading as it is only 43 colts.
Since the initial analysis two years ago I knew it could be improved.
In the last few weeks I wrote programs to improve the ratings.
The problem was the average for many inbreeding types did not vary far from the average for all 37,057 colts (93.778).
Almost every pedigree will have a few different inbreeding types, and the task was to as far as possible know how much each type contributes.
Think of it like 37,057 bags of licquorice allsorts, with a number on each bag giving the bag an attractiveness rating.
But the bags were not precisely filled by machines, with a fixed number of each sweet type - black and white rectangular pieces, yellow and white rectangles, white cylinders wrapped in licquorice, circular yellow pieces with a liquorice centre, and the nice round light blue ones with small balls on them (and pink ones).
Imagine the bags were filled by hand and the count of each type of licquorice sweet in each bag differs greatly.
You can count the black and white rectangles and get the average rating on the bags with 1 b&w rectangle, 2 b&w rectangles, 3 b&w rectangles and so on.
But that average ignores the other sweets in the bag, and they are raising or lowering the average.
What I did in the last few weeks was, for example, take all the pedigrees with one occurrence of a sire duplicated (i.e. twice in pedigree) producing two sons.
It was 16,074 of the 37,057 colts.
Then I counted the duplications of the other 17 inbreeding types (9 sire types, 9 dam types) in those 16,074 pedigrees.
I remove the influence of the other 17 inbreeding types.
The program to reassess the rating for each inbreeding type is 1700 lines, very repetitive.
Then it was simple to copy the program, make a small adjustment, and run it for the next inbreeding type, and so on.
GRAPH
The bottom axis should start at 0 and go to 7 (not 1 to 8 as shown).
The average of 93.778 was graphed, a straight line, but a white line does not show up well on a white background.
Where a graph line suddenly stops e.g. purple line 103.3 at count 4 (actually 3), that is because there were no high occurrences of that inbreeding type.
You want your colt to have the inbreeding types "light blue line"; "royal blue line", "cyan line"; "purple line".
You do not want your colt to have inbreeding types "yellow line" or the line that goes off the page on the right at 94.5 for 7 occurrences.
Where the graph lines are concentrated in the bottom left corner is where the high numbers of colts are i.e. the low sire inbreeding counts.
You want your colt to have a high occurrence count of the best types of inbreeding. A low count of these will not improve the colt above the herd.
A general rule is you want opposite sexes in an inbreeding.
If you have a sire duplicated you do not want two sons of that sire.
The same for a duplicated dam. You do not want two daughters from her.
Better to have a son and daughter of a duplicated sire or two daughters.
The problem for breeders is they already have the mare.
The sires available at stud may not give the inbreeding matches required.
Look for a mare that matches the sires now at stud.
Counts for all nine sire inbreeding types in colts:
187,925 (0, zero); 75,251 (1); 35,127 (2); 11,723 (3); 10,046 (4); 4,154 (5); 4,000 (6); 1,925 (7); 1,510(8); 788 (9).
You can see that a count of 0 or 1 of an inbreeding type is very common (shown on the graph as 1 and 2), and of course average colts are very common.0 -

Nothing obvious from the results, but I only glanced at them.
It is difficult to assess dam inbreeding for one reason.
There is seldom more than one dam inbreeding group, with only 9.4% of the 159,222 having dam inbreeding in six generations.
Pedigrees with female (dam) duplications: (0) 90.6%; (1) 5.6%; (2) 2.9%; (3+) 0.9%.
This is the occurrences of dam inbreeding groups in colts + geldings + fillies = 159,222 horses.
occ Perc
0 90.6%
1 5.6%
2 2.9%
3 0.4%
4+ 0.5%
"everything is learned by comparison"
At best in the 159,222 horses you are comparing large numbers with 0 occurrence (144,250) against those with 1 occurrence (8,928), 2 occurrences (4,618); 3 occurrences (583).
... there is not enough contrast.
However, with 9 dam inbreeding types, and colts, geldings, fillies = 9 x 3 = 27
... in 24 of 27 cases having 1 dam inbreeding group gave increased average ratings over 0 dam inbreeding group.
... in 8 of 15 groups (not 27 due to small count groups bypassed) those with 2 dam inbreeding groups had higher average ratings again over those with 1 inbreeding group.
... 5 of the 7 with 2 inbreeding groups who were not higher than 1 inbreeding group were still higher that the 0 inbreeding groups.
Comparing the colts (avg rating 93.8) to the geldings and fillies (avg rating ~ 74.5 each) might show something other than mentioned in a post above.0 -

This is a list of English Derby winners from 1945 to 2016, and a few earlier important Derby winners.
It shows (in my data) the number of offspring they produced (prog1),
the number of offspring those offspring produced (prog2: grandchildren),
and the number the grandchildren produced (prog3: great-grandchildren).
Sires born after around 1990 would have few great-grandchildren by 2019, those born after 2010 would have few progeny at this stage.
Up to around 1970 many stallion owners restricted their stallions to 40 mares a year.
A few sires had short stud careers: Troy; Golden Fleece; Shergar
Many sires were exported to Japan (High-Rise; Commander-In-Chief; Lammtarra; Oath), Australia (Quest For Fame),
USA (Nijinsky; Secreto), and would be under-represented in my data.

Before buying a mare for breeding it would imo be a good idea to check the sires in her pedigree, paying attention to the sires of females in her pedigree, and especially her dam line.
If the sires there have produced few prog1, prog2, prog3 (see Reference Point above) then that sire may not be passing quality to its foals.
And if you want to have inbreeding duplications of famous sires in a foal pedigree then a mare with sires in her pedigree with few offspring is not attractive.0 -

Northern Dancer was possibly the most influential sire of the 20th century.
I look at many six generation pedigrees on screen (2+4+8+16+32+64 = 126 ancestors).
Northern Dancer (b 1961) is in almost every six generation pedigree.
He if often duplicated in pedigrees, the majority of times as the sire of sons in the pedigree.
I even had to widen a count field from one digit to two digits as a pedigree had twelve sons of Northern Dancer in six generations (out of 63 sires!).
The average thoroughbred generation is about eleven years.
Northern Dancer was born in 1961, 58 years ago.
He should feature, on average, in the 5th generation of horses born in 2019, and in earlier generations from his first crop in 1966 onwards.
I decided to analyse in detail the basic numbers of offspring of Northern Dancer (519 progeny, 19,193 grand-children, 95,225 great-grandchildren) in my data in more detail.
If you split the numbers into colts, geldings, fillies you see that Northern Dancer's 95,225 grand-children are predominately the produce of his stallion sons, 88,967 horses (93%).
He has 14.2 times more great-grandchildren decended from sons than from daughters (88,967/6,258 = 14.2).
This reflects the 1970s importations of sons on Northern Dancer into Europe, and the re-exportation of many of those sons back to north America as sires.
The great horse St Simon (b 1881) was so successful as a sire there was a rush to buy his sons. Over 100 of his sons found places at stud. And the sire line of St Simon died out.
You might point out that there is an imbalance in the numbers.
Surely Northern Dancer colts should have produced equal numbers of colts and fillies?
I have 4,004 colts (male); 2,115 geldings (male); 11,558 fillies (female) ... 6,119 males, 11,558 females, not 50%/50% but 34.6%/65.4%.
Than shows about 5,500+ males disappeared, probably because they were unsuitable for training. And many fillies were not retained.
These numbers are what is in my data, and are not the full crops.
A bit of trivia: the analysis of 28,868 sires and 266,750 dams born from 1900 onwards to produce the above information for each takes 29 minutes on my slower PC.
Is this "information" of any practical use?
It is backward looking. It looks at the horses produced by sires and dams who lived decades ago.
The data might be useful if you want to look at the breeding performance of sires and dams in the 3rd, 4th, 5th generation of a pedigree.
You want sires and dams who produced many children, grand-children, great-grandchildren (sorry about the use of "children").
You want to avoid sires and dams who failed at stud i.e. were bad producers / unpopular.
If you are looking at a sales catalogue you will see the black type of the dams on the dam line, and also the black type of the relations of those dams.
But you will have little idea of how many progeny trace back to the 5th dam, 4th dam on the dam line, or the same for the dam line of the sire of the lot on offer.
Here is a small summary of 2,180 dams born in 1961, the same year as Northern Dancer (the year 1961 is irrelevant, just taken at random).
1,723 dams born in 1961 had less than 10 great-grandchildren; 396 dams had 10 to 99; 50 dams had 100 to 999; 11 dams had 1,000+ great-grandchildren.
It is obvious that the 11 dams who produced the greatest number, 1,000+, produced these through sons or grandsons that were sires.
Can you name these dams born in 1961 who produced 1,000+ great-grandchildren? Thought not.
Can you name the 292 dams born in the 20th century who produced 1,000+ great-grandchildren?
These questions show how difficult it is to read a sales catalogue pedigree page trusting your memory to identify important horses.
What I will do in the next year is use this progeny data, and mark the ancestors of mares on offer at the 2019 breeding stock sales with the progeny counts.
It should be possible to do this in a few minutes.
In the next few posts below I will put up some sire and mare numbers.

The fear is finding a box of books or a cupboard of books I missed.0 -
This is a thread I started when my username was diomed.
In Jan/Feb 2017 I wrote pedigree inbreeding analysis programs and compared the rating of 159,222 horses to the inbreeding in those horses.
The inbreeding was split into 18 different types of inbreeding.
Examples of three different inbreeding types are: two sons of a duplicated sire; son and daughter of a duplicated sire; two daughters of a duplicated sire.
I found that different inbreeding types gave different results / different influence on the foal.
It was always my intention to revisit the work and re-write the programs.
There were a few small errors in the earlier version.
Other reasons for a re-write were improved (expanded) analysis, and to increase the pedigree analysed for each horse from six generations (126 ancestors: 2+4+8+16+32+64).
During the present coronavirus lock-in I have worked on the basics.
I expanded the pedigree from 6 generations (126 ancestors) to 10 generations (2,046 ancestors), 16 times the number of ancestors.
I have no idea if bigger is better.
At this stage all I have done is write a program to fill a file with 2,046 ancestors of a horse, and mark and number the duplication groups (01dup; 02dup; 03dup ) in those 10 generations (and the horses behind the duplications i.e parents, grandparents and so on).
An example is the sire Galileo (b 1998).
I always thought his pedigree was boring and it was difficult to explain where he got his quality.
If you look at Galileo's six generation pedigree you see only two duplication groups: Native Dancer (m) 4x5 daughter and son produced; Nasrullah (m) 6x6,6 two sons and one daughter produced.
This looks like a very average inbreeding pedigree.
Of course you can say he was by multiple times champion sire Sadler's Wells out of the Arc winner Urban Sea and that explains his quality.
What I found when the program ran over the 2,046 ancestor in the first 10 generations of Galileo's pedigree is 58 inbreeding duplication groups.
At this stage I have only run the program over a handful of other horses and the usual result is about 36 to 40 duplication groups.
I do not know if the large number of inbreeding groups in Galileo's pedigree is rare, or if it is significant.
I will now go back and add features to the basic duplication group identification: support horses (i.e. sire and dams that are parents of the duplicated horses); full sibling identification; comparing the duplication groups to each other to see if they have horses in common.0 -
Part of the analysing inbreeding theory is that if a sire is duplicated in a pedigree two or more times it must be through a son and daughter or two daughters if you want a good horse. If Northern Dancer is twice in a pedigree (must be in the sire side and the dam side) I want to see a son of his and a daughter of his (or two daughters).
However, in modern pedigrees duplication groups with only sons of a duplicated sire are very, very common.
In my opinion that produces slow horses.
I found this remarkable.
For the last hour I have gone through the 58 duplication groups in Galileo's ten generation pedigree, 50 duplicated sire groups and 8 duplicated mare groups.
56 of the 58 duplicated sire groups are represented by offspring of both sexes or by daughters only.
Two groups had sons only of the duplicated sire: the 28th group, Dark Ronald (1905) had 9 sons; the 57th group, Bend Or (1877) had three sons.
21 duplication groups produced daughters only.
You will notice that there were 27 duplication groups in the pedigree before you get to the Dark Ronald group which is in the 8th generation (2 horses); 9th gen (3 horses); 10th gen (4 horses).
The above analysis was done by hand. I would prefer to write a program to do the counts automatically, and to test many other horses in a batch.0 -
I am rearranging the directories on my PC and found this 2016 analysis of horse names. Perhaps I posted it on the forum at the time.
It shows the words most commonly used (not the full name).

In post 86 above I mentioned analysis of Galileo's pedigree.
His ten generation pedigree is almost exclusively desirable inbreeding, with almost no negatives.
I checked a few famous sire failures. Their pedigrees had negatives.
This test was only on a handful of horses, top runners also sire failures.
Old pedigree program
In Jan/Feb 2017 I wrote a database program that analyses inbreeding in the first six generations of pedigrees (2+4+8+16+32+64 = 126 ancestors).
The inbreeding results were compared to the ratings of 159,000 horses (horse by horse).
I found there was a strong relationship between certain types of inbreeding and higher ratings. The reverse was true. A few inbreeding types gave lower ratings.
A son and daughter of a duplicated sire (i.e. a sire twice or more in a pedigree and on both sides) was much better than two sons of a duplicated sire (the most common inbreeding).
The inbreeding types are many:
Duplicated sire: son & daughter; two sons; two daughters
Duplicated dam: son & daughter; two sons; two daughters
Other duplications are offspring of full siblings (horses with the same parents). These can be full sibling brothers (e.g. Sadler's Wells and Fairy King; Kris and Diesis); or full sibling sisters; or a full sibling brother and sister (e.g. Hector Protector and Bosra Sham) and they can produce son and daughter, two sons, two daughters.
There can also be 7/8 siblings or 3/4 siblings (e.g. two horses by Galileo out of Danehill mares), and their offspring.
Another complication is an inbreeding group can be more than two sires (or two dams). A sire duplicated 3, 4, 5 or more times is common.
New program
For about three months I have been writing a new pedigree analysis program.
There were a few programming errors in the Jan/Feb 2017 program, and the analysis it generated was too simple.
This time I went for a bigger pedigree for each horse, 10 generations (2,046 ancestors), or 16 times as many ancestors.
I was not too concerned about analysing the 9th and 10th generations but extending the analysis beyond six generation was informative.
What I found in Galileo was two horses in his first six generations on the sire side became part of a duplication group when I took in the 7th and 8th generations on the dam side.
There is no rule that everything is known from the sire and dam (many hold this view); or from a three generation pedigree (sales catalogue); or from four generations (Dosage Index calculation).
Work done:
Duplication groups identified (can be up to 70 groups in 10 generations).
Full Siblings identified.
Support horses identified (parents or grandparents of duplicated horses outside the duplication groups)
7/8, 3/4 and other near siblings identified (15/16; 5/8).
Work to do:
Comparison of duplication groups to each other (are they related?)
Marking of 7/8, 3/4 siblings.
The program for these two is done and running but not built into the main program.
This morning a program is comparing 146,000 horses (146,000 vs 146,000) and this program will be built into the main program. If there are 40 duplication groups it will compare 40 vs 40.
Personal computers
2008 PC: stopped working in May 2020, and has been brought back to life.
It is with the IT repair person. He is building another PC that will become my reliable PC for old software.
2006 PC: I am using this to write the new program. It is three times faster than the 2008 PC.
2020 PC: This has nothing on it, and I use it for browsing boards.ie, racingpost.com and other internet sites.
My plan is to use two or three PCs at once to run the new program.
My old program analysed 51 pedigrees a second on the 2016 PC. The new program analyses 2 pedigrees a second on the 2016 PC.
I timed the new program section by section as I wrote it looking for small time savings.
An example of a saving is the comparison of 146,000 horses (list 1) vs 146,000 horses (list 2) (the same horses).
If you compare A (list 1) v B (list 2) you do not need to compare B (list 1) v A (list 2).
As far as possible I do the work before I run the analysis ("here is one I prepared earlier").
Instead of looking up the sire and dam of a horse (2 horses) the new program looks up the parents, grandparents, great-grandparents (14 horses).
What use is a program that analyses pedigrees?
If a program can analyse one pedigree it can analyse many pedigrees.
I think the main benefit is analysing breeding stock.
There are breeding stock sales in IRE, GB, FR in Nov/Dec each year.
If you have the pedigrees of all the mares at those sales (about 3,000) you can prepare test-mating of those mares with every stallion in IRE, GB, FR, and pick the best stallion/mare combination.
While you are at it you can also analyse the pedigree of the foal the mare is carrying (almost all mares sold are pregnant), and her breeding potential (if a filly).0 -

The above two pieces are not in the main program yet.
They may be slow. It might be best to leave them out of the main program, but could be used later to reanalyse small samples of good horses.
Program speed analysing one horse is about 0.561 seconds each horse on a fast PC.
My old 2017 program took about 0.020 seconds each horse but analysed a lot less pedigree.
The program uses a load file that can contain an unlimited number of horses.
The program loads one horse, analyses it, puts the result in a results file, then loads the second horse and repeats.
In the past few weeks I learned new programming tricks, but the reality is I learned stuff I should have known and used earlier.
The slow part of the program below, dup_all, can be adjusted.
At present it finds as many duplicate groups as possible in 10 generations.
The most I found is about 65, but I can quickly change the program to find e.g. the first 35 groups and analyse those only, and that will increase speed.

These last two pieces are finished, and are in one program.
The running time for that program is 0.031s each horse.
This is a bit of a cheat.
The main program takes about 0.6s a horse.
To do this final analysis for each horse would take another 60 seconds each horse i.e. increase the analysis time per horse from 0.6s to 60.6s.
Instead of running the analysis for each horse (about 60 seconds) I identified the horses in history that are likely to be in almost all pedigrees.
It was 1,840 horses (from c 1900 to 2020).
The analysis was 1840 x 1840 / 2 = 1,692,800 "horses" and a separate program took 11h 34m to do this.
That analysis is in a results file that is looked up by the final version of the program. A lookup that takes 0.031s is better than about 60s if done live.
If I find horses not in the 1,840 I will add them and add their analysis to the results file. In time almost all important ancestors will be covered.
The next step is to run the total program with a big load file of thousands of horses, and a big results file to take the output.
This might throw up a few issues but hopefully nothing much.
The work has taken almost five months.0 -

Tonight I finished the pedigree analysis program, but these things have a habit of never finishing.
The results file has 75 numbers on one line for each horse.
The next step is running the program with a large load file of a few thousand horses.
Often programs stop for a simple reason such as one results field being too narrow.
In Jan/Feb 2017 I compared the previous pedigree analysis program results to horse ratings, and that is where this is heading.0
