    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.

    Most of y'all Caucasians are born with blue eyes

    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

    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.

    (OK ShooterSF even if you are mistaken the important thing is not to admit it but dig your heels in and use any argument to back it up.)

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

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

    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!!!!
