Are we all born with blue eyes?

pimpy_c

This has been an ongoing argument between myself and my girlfriend so I have to find out. Are we all born with blue eyes? She says yes, I say no.

Now I've googled this but a lot of sources aren't very reliable. Some say most people are while others say we all are. Somebody please tell me.

I cane believe Im answering this seriously but no. Brown eyes are actually the dominant gene. So if one parent has blue eyes and the other has brown then the child will have brown eyes.

asdasd

Most of y'all Caucasians are born with blue eyes

Quazzie

Most babies are born with blue eyes and then some change to brown within the first six weeks. But some babies are born with brown eyes so there is no definitive answer

EDIT: I might be racist but I was only talking about white babies

themadchef

Ongoing argument?? Find something better to argue about........


Ask her has she put on weight, thats a good start.

I've always heard this. Is it an old wives tale? I'm pretty tanned with dark hair and eyes and I was born with really dark blue eyes.

Question 1. Then why do some people have different colour eyes to their siblings?

Queston 2. Why do arabs all have brown eyes? Is it cause of the dominance of brown eyes?

Afaik this is only true for kittens.

Lets answer number two first as its the easier one. Eh, Yes.

Now for question one. Women hide affairs well. QED.

Boom_Bap

Born with Blue eyes = No.

But apparently from when the eyes are first made inside the lovely warm lady bits, they start off as blue, but they change during growth of the feutus.
I have not looked inside nearly enough pregnant women to confirm or deny this.

Ok I am training as a midwife so this is the closest I can give to an accurate answer 90% of children are born with blue eyes, which within the first 6 weeks change to the colour that is most likely going to be the colour they remain for the rest of their lives. the other colour the eyes are when the baby is born is brown unless the baby has albinism in which case the are scarlett red in rare cases.

Yes some people notice that this occurs also with puppies and kittens, I suppose it must be a mammalian trait

Not up here in ireland it isnt, that is for the world. And i believe there not many asians with blue eyes. Or africans, indians, arabs, pygmies or monkeys.

Because the child needs to have the blue-eye gene from both parents in order to have blue eyes. Let's say both parents are Bb, which means they have brown eyes but carry the blue-eye gene. I think you have to construct a grid thing for this this but it always goes- Child 1- BB (brown eyes), Child 2 Bb (brown eyes), Child 3 bB (brown eyes), Child 4 bb (blue eyes). Of course, doesn't always work out in that order.

Not being racist but you'll probably dealing with Irish babies, i'd say most babies are born with brown eyes in the world scheme of things

Now hopefully this isnt taken badly but you would not believe the amount of foreign nationality babies born in the Dublin hospital I am doing my training in, and with a large number of Asian and African women giving birth there I can tell you,

Asian women mostly have blue eyed babies and yes the African women have the most brown eyed, but with all humans there is always the exception too:)

Nope. A person with blue eyes will have a bb combo. A person with brown eyes can be either Bb or BB. If they are Bb then there is an equal chance of them passing the blue eyed gene onto their kids.

I have green eyes (they were blue when I was born).

My wife has brown eyes (no idea what they were when she was born as I didn't know her then)

Our first child has brown eyes, they were very dark brown when she was born.

Our second child has blue eyes. Very blue eyes!!!!

I'm one of eight children in my family.Mother has green eyes, father has blue eyes.I'm the only one to have inherited the green eyes, all the others have mad blue eyes.I had blue eyes when I was born though.

Wow, that's exactly the situation with me and my siblings, me being the only one with blue eyes (youngest).

But my dad had green eyes and my mum as brown. But both could carry blue gene?

metaoblivia

My Dad has green eyes and my mom has brown eyes. Both my brother and I were born with dark brown eyes. But my brother's second ex-wife has blue eyes, and their son was born with blue eyes. He was DNA tested too, so we know he's my brother's son. I'm guessing my nephew got a recessive green eyes gene from my brother and a blue eyes gene from his mother.

Hmm At first I thought this was an obvious one. Your first child was right and the second was the result of my answer to question one posted above, however I then realised that still doesnt make sense.

So this is how it usually happens, Im not saying it did, don't get angry with me. The woman, nefariously promiscuous, has a lesbian affair with a woman (with blue eyes) on the rags who's egg slips into "our" woman.
Our woman then goes and has an affair (damn women) with a blue eyed fella whose blue eyed sperm infilitrate the borrowed egg and hurrah. Perfectly scientifically blue eyed babe.

Sorry to be the one to break it you.

I was half tempted to check that my third child wasn't swapped in the hospitlal as he has brown eyes! Child one has pale blue eyes,child two dark blue and child four has green eyes! I have greeny grey eyes and hubby has grey too. I asked the GP and he said it was quite possible that we would have a brown eyed child. On checking with relatives someone way back had brown eyes.

Nothingcompares

ok i haven't checked this on google and no one seems to have already stated it.

the truth is, as far as i know, babies are not born with the pigment that produces eye colour. Yes of course, eye colour is genetically controlled but the pigment takes some weeks (6 weeks?) to be produce. The eyes look blue because that's just the way the light reflects the colourless eyes. As the baby develops their eye colour pigmentation will become more and more lucid and you see the greens/blues/browns.

actually i just googled it

An infant's eye color is determined by a substance called melanin. Melanin is a dark pigment contained in the iris, the structure that controls how much light is allowed into the eye. The color of the iris is determined by the amount of melanin in the iris. Light eyes have very little pigment, whereas darker eyes have a lot. In newborns, the pigmentation process of the iris is not yet complete. Babies with darker skin are usually born with dark eyes that stay relatively dark. Iris color in lighter-skinned babies is usually a blue or bluish-gray color at birth, then change as they grow. Melanin production changes during the first year of life, usually resulting in a darker, deeper eye color.

Permanent eye color is not set until a baby is at least nine months old, so wait until your child's first birthday to determine what color they will be.

An infant's eye color is influenced by the eye color of their parents. Eye color is often studied in the field of genetics because of its inheritance patterns, but is still not fully understood.

My understanding from a biology course I took when I was 14, was that brown eyes are the most dominant, followed by blue eyes, with green being the least dominant. So your Dad most likely had the green gene, but your mom had the blue gene and that won.

your explanation doesn't make sense.

In order of dominance Brown (br) Blue (bl) Green (gr).

Her mother has to be grgr. If she was Blgr she'd have blue eyes. Blue is dominant to green. Her dad could be Brgr (have brown eyes and carry green gene). But any mixture between the parents

Brbl (brown) Brgr (brown) grBl (blue) would not yeild green eyes.

my explanation is:
1. eye colour is actually more complex then we've assumed
2. both have blue eyes or both have green eyes but ones "shade" fo blue looks green

She said her mother had brown eyes and her father had green eyes. So her father is grgr, and her mother may be Brbl. In which case, her mother would pass on the brown gene to the older siblings, but she ended up with the dormant blue which would override the father's grgr.
