In humans, brown eyes (b) are dominant over blue (b)*. a brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. draw the punnett square that illustrates this marriage. what is the man’s genotype? what are the genotypes of the children?

 The man is Bb, the two brown eyed children are Bb (B from dad and b from mom) the blue eyed child is bb. B (brown) is dominant where b (blue) is recessive. In order to be blue eyed you must have gained the recessive b from both parents as B will always dominate over b, so mom is bb. Because they also had a blue eyed child, it tells you that dad is B dominant because of his brown eyes and has a b recessive in order to pass the recessive b to his blue eyed child.
