6074.Ge.r.html Hope it helps! Re: white parents having a black child... I seem to remember reading an article a few years ago about a black child being born to white parents. The reason given for this was that the mother's great, great grandmother was black, and the new baby had inherited enough of his/her predecessor's genes to be 'darker' than it's parents. As this was a few years ago, I can't be more specific than that, sorry.

I have blue eyes, as does my husband. Our eldest child has very brown eyes, not just browny blue but definately brown. Our youngest child has blue eyes. My paternal grandmother had brown eyes and my husbands maternal grandmother has brown eyes. Everyone else has blue eyes. Our eldest daughter is my husbands child and I would have DNA to prove it, but I don't need to as WE know that she is my husbands child. It would be nice to know the chances of this hapening though!
I believe geneticists once believed a single gene was responsible for eye color. It is now known that at least three genes are used and relationship is quite complex. The three gene model still does not explain how two blue eyed parents can have a brown eyed child. This suggests yet another gene is involved that influences eye colour.
