A blue-eyed woman whose parents had brown eyes married a brown-eyed man whose mother was blue-eyed

A blue-eyed woman whose parents had brown eyes married a brown-eyed man whose mother was blue-eyed and whose father was brown-eyed. What children can appear in this family (in relation to this sign)? Write down all possible genotypes of all family members.

The eye color gene is inherited in a complete dominance pattern. A – brown eye color, and – blue.

The woman is blue-eyed, homozygous for the recessive trait (aa). Consequently, her parents were heterozygous (Aa).

The man is brown-eyed, but since his mother was homozygous for a recessive trait, his genotype contains a recessive gene (Aa). Genotypes of his parents: mother aa, father Aa or AA.

The likelihood of having children:

P: aa x Aa

G: a X A, a

F: Aa – 50% (brown eyes)

aa – 50% (blue eyes)
