Question:

Can someone explain prominent and recessive genes to me and the difference?


Best Answer - Chosen by Asker: Dominant ones rule, recessive ones get carried along. Someone with brown eyes may have one brown-eyes gene and one blue-eyes one. He will have brown eyes because brown is dominant. If he marries someone who also has one brown-eyes gene and one blue-eyes one, their children will inherit ONE gene from both. There are four possibilities for the children:

Br Bl - Brown eyes (Just like mom & Dad)
Bl Br - Brown eyes
Br Br - Brown eyes
Bl Bl - Blue eyes

The child with two brown-eyed genes can never have a blue-eyed child. If "Bl Bl" marries a fellow Bl Bl, all their children will have blue eyes. The Br Bl children will carry both; they will, just like dad, have brown eyes but carry the blue eyed gene.

Some genes are neither. Children with one black parent and one white one come out colored like coffee with a lot of cream in it, not black, white or spotted like a Holstein cow. The skin color gene blends.

This is an over-simplification. There is more to it than that, which is why eye color ranges from the deep deep brown (almost black) of Asian people through light brown, hazel, green, violet and grey to the light blue of the Swedes and Danes.
