A red-eyed man married a blue-eyed woman, they had 2 boys, one eye was brown

A red-eyed man married a blue-eyed woman, they had 2 boys, one eye was brown, the other blue, find the genotypes of the whole family?

In this case, the opposite signs of both parents were transmitted and manifested to the children. This suggests that a man with a brown color has a heterozygous genotype, i.e. he is the carrier of a recessive gene (g) and a dominant gene responsible for brown eyes (G). In a woman, both genes are recessive, and therefore the eyes are blue.

Their genotypes are as follows: Gg (male) and gg (female).

One son received G from his father, and from his mother – g (Gg – brown color), and the other from both father and mother according to the recessive gene g (gg – blue color).
