Question

Blonde hair (b) is recessive and black hair (B) is dominant. A woman with black hair marries a man with blonde hair who is homozygous recessive for blonde hair. Predict the outcome of their children when the woman is homozygous for black hair. 1) How many of the offspring would you expect to have blonde hair ? (2)How many of the offspring would you expect to have black hair? Thanks in advance.

Answer 1

All their kids would have black hair. They'd all be heterozygous for it. Try making a Punnet Square. All the offspring have Bb. And you're welcome
