Answer to Question #101385 in Genetics for moya kenward

Question

a man has brown hair and brown eyes with the genotype AaBB and he has children with his wife who has red hair and green eyes (aabb). If the allele for hair is A, and the allele for eyes is B, could any of their future children have green eyes?Explain

Answer 1

For eye color, the man's genotype is BB, and the woman's genotype is bb.

Allele B determines brown eyes, while allele b is for green eyes.

For the child to have green eyes, its genotype should be bb.

The woman can donate allele b, while the man cannot. He will always donate allele B, which will result in brown eyes.

Thus, the child cannot have green eyes.
