In fruit flies, eye shape is an X-linked trait. Round eyes (XG) are dominant to almond-shaped eyes (Xg). In the P generation, an almond-eyed male mates with a female that is homozygous for round eyes. What is the expected phenotype ratio (in percent) of the F2 generation from this cross? Round-eyed female: 100 75 0 50 25 Round-eyed male: 25 0 75 100 50 Almond-eyed female: 0 75 25 50 100 Almond-eyed male: 0 100 75 50 25
