Is it possible for an african-american and a caucasian to produce a child with blue eyes? I remeber learning in high school biology that it was not possible. I'm african-american and my husband is caucasian and we have a daughter with brown eyes, much to his disappointment. His nephew also married and african-american woman and they have daughter with blue eyes. Is this possible?

Brown eyes are dominant. A recessive gene can win out if it's present on both sides. Did the woman have a mother or father with blue eyes?

I don't know if the mother has parents with blue eye, very unlikely though. I will find out and write back. Is this the only way this is possible? Thanks for repsonding.

Like Aya said, Brown is dominant. Meaning if you have brown eyes, chances are high that your kids will have brown. On the other hand, blue is recessive, so it's more likely that two blue eyed people will have a brown eyed baby than two brown eyed people to have a blue eyed baby.

Since blue is recessive and black is dominate (now from here on I'm assuming that you both are homozygous for your eye color traits) then you'll only have heterozygous children. This means that your children with have both traits but the dominate trait will show through. Now if you are heterozygous than you have a 50-50 percent chance to have a child with blue eyes or brown eyes.
