If a brown-eyed man marries a blue-eyed woman and they have seven children, all of whom are brown-eyed, what is the father's genotype? What are the genotypes of the children?

The father has to be homozygous for brown eyes(BB) if his children all have brown eyes. Since, the brown eye gene is dominant over blue eyes. All his children will be heterozygous for Brown eyes (Bb).

The father's genotype is homozygous dominant (BB), while the mother's genotype is homozygous recessive (bb). All seven brown-eyed children have the heterozygous genotype (Bb). This inheritance pattern occurs because brown eyes are a dominant trait over blue eyes.
