Determine the likelihood of having a baby with blue eyes if a woman has blue eyes, and a man has blue eyes, and he is heterozygous for this trait.
Given: A – brown eyes (dominant), and – blue eyes (recessive).
The man is brown-eyed and heterozygous for this trait, which means his genotype is next Aa and he forms two types of gametes A and a.
The woman is blue-eyed and her genotype is aa and she forms the following gametes a and a. She is homozygous for this trait.
After crossing, a generation is formed with the following genotypes: Aa and aa. The probability of having a baby with blue eyes is 50%. The genotype ratio is 1: 1.
