In a hypothetical scenario, three women claim that Bill Clinton is the father of their children. Bill has blue eyes. The eye colors of the women and their children are as follows: 1) a blue-eyed mother with a brown-eyed child, 2) a brown-eyed mother with a blue-eyed child, and 3) a brown-eyed mother with a brown-eyed child. Considering that the gene for brown eyes is dominant over the gene for blue eyes, let's evaluate whether it is possible for Bill to have fathered each child. 1) For the blue-eyed mother with a brown-eyed child: If both parents have blue eyes (bb), they cannot have a brown-eyed child (B_) because neither can contribute the dominant allele for brown eyes. 2) For the brown-eyed mother with a blue-eyed child: This is possible if the mother is heterozygous for eye color (Bb) and contributes her recessive blue allele (b) to the child, and Bill, who has blue eyes (bb), also contributes a blue allele. 3) For the brown-eyed mother with a brown-eyed child: This is also possible, regardless of whether the mother is homozygous (BB) or heterozygous (Bb), as Bill would contribute a blue allele (b), and the brown allele (B) from the mother would be expressed in the child's phenotype.
