As many of you know, I’m waiting impatiently to find out what color hair and what eyes Caleb will have. In trying to figure it out I’ve discovered that eye color and hair color is not the simple "Bb" vs "bb" they taught us in elementary school science. Now they think eye color is primarily determined by how one gene interacts with three other genes! At least that’s what I got out of the article. I did learn one really interesting fact:
Green eyes
probably represent the interaction of multiple variants […] including perhaps the red-hair gene.
So green eyes and red-hair are related!
