In a purely hypothetical situation, three women all claim that Bill Clinton is the father of their child. Bill has blue eyes. The eye colors of the women and children are: 1) blue-eyed mother, brown-eyed child 2) brown-eyed mother, blue-eyed child 3) brown-eyed mother, brown-eyed child. Given that the allele for brown eyes is dominant to the allele for blue eyes, evaluate wether it's possible for Bill to have fathered each of these children.

Bill could not have fathered the first child as that would mean that the woman had brown eyes, which she did not. A yes for the second, as long as the mother had a recessive blue eye gene within. A yes for the last, the mother was brown eyed and the child was brown eyed, taking the dominant allele. No for 1, yes for 2 and 3.
