Question:

Is it possible for two blue eyed parents to have a brown eyed baby?

Thoughts?


Best Answer - Chosen by Asker: High school biology taught me that two blue eyed parents can only have blue eyed children, because the gene for blue eyes is recessive.

It was the early nineties, so I'm unsure of the correct representation, but I think it was B for brown, and b for blue. To get the colour brown, you can either have BB, Bb, or bB. Since B is the dominant gene, it will always win over blue, so even if you have the gene for brown, and the gene for blue, your eyes will be brown.

The only way you can have blue eyes is with bb. Two blue genes. While it is possible for two brown eyed parents to have a blue eyed child (if they each give a child their b gene), if you and your partner both have blue eyes, you only have the genes bb bb to work with, so can only give your child bb.

At the time, they weren't sure what caused hazel eyes, but perhaps they've discovered more about it now?
