Please help me answer this genetics question and can you show me the punnet square?
In humans, normal pigmentation dominates no pigmintation (albino). Black hair dominates blonde hair. An albino person will have white hair even though he/she may also have the alleles for black or blonde hair. An albino male who is homozygous for black hair marries a woman who is heterozygous for normal pigmentation and has blonde hair. What colors of hair can their children have, and what is the probability for each hair color? Thank you.

There is a 50% chance the children will have black hair, and a 50% chance the children will have blonde hair. Black hair is dominant, so let B represent black hair. Blonde hair is recessive, so let b represent blonde hair. The father is homozygous for black hair = BB. The mother has blonde hair = bb. The punnet square would have two Bb crosses, and two bb crosses.
