...andevryone else has blue eyes)

Its entirely possible for a recessive gene to pop up, but if everyone on both sides of the gene pool has blue eyes, thats probably what you'll get. My moms side has all blue eyes, and my dads has all brown, but I've got bright green eyes. I wouldn't hold out too strongly for blue if I were you.

Hi, My husbands family all had blue eyes, i have brown i thought at least one of my children would have had blue eyes, one has grey eyes, one has brown eyes. So you never know brown eyes may come out somewhere along the line.

It used to be thought that brown eyes are carried by what is known as a dominant gene: If a child received a brown-eyed gene from one parent and a blue eyed gene from the other, it will have brown eyes. Because of this, it was considered extremely rare to have a brown eyed baby in a family where everyone else has blue eyes, although it is not impossible. The opposite (a blue-eyed baby in a brown-eyed family) is still unusual but much more likely. Indeed, blue-eyed men actually have a subconscious preference for blue-eyed women partners because of the fact that they stand a better chance of spotting any child which doesn't belong to them.However we now know that eye colour is polygenic (a combination of different genes) and therefore the determination is more complex. However it does remain the case that it's very unusual for a brown-eyed baby to be born to two blue-eyed parents.

Yes. Blue eyes are recessive and brown is dominant. It is possible to get any other colour from two brown eyed parents i.e blue, green, hazel but it is a genetically unlikely to get brown eyes from 2 blue eyed parents. It can happen, however. Eye color is a complex trait that depends on the state of several interacting genes. The gene that usually decides the issue (blue eyes or brown eyes) is the OCA2 gene on chromosome 15. But it comes in different strengths. A person with a weak form of the OCA2 gene will have blue eyes. Likewise a person with a strong form will have brown eyes. An individual also has other eye-color genes that each has a say in the final eye-color outcome. For example, if one of these lesser genes is strong, it can make the weak form (blue) of OCA2 work much more effectively — almost like the strong form (brown). Then the eye color may be a light brown or muddy grey. In fact, the resulting color can be any shade of brown, hazel/green, or blue depending on the strengths of the interactions.So it is against the odds but it can happen. However, if there were two parents with very blue eyes and a brown eyed kid turned up i think it would be fair for the dad to question the paternity ! He could be the dad though.Check out this link http://www.genetree.com/resource/eye...lculator.phpIt suggests what outcomes are unlikely and they use this for broad paternity tests (i know the paternity is not in question here but it helps to illustrate the point). They say certain fathers are 'not excluded or likely excluded' from being the father but it doesn't mean they are right. Back in the day people used to think 2 brown eyed parents could not have a blue eyed child- they were of course completely wrong.
