In Drosophila, white (w), eosin (we), and wild-type red (w+) are multiple alleles at a single locus for eye color. This locus is on the X chromosome. A female that has eosin (pale orange) eyes is crossed with a male that has wild-type (red) eyes. All the female progeny are red-eyed; about half the male progeny have eosin eyes, and about half have white eyes. Assume the female has two X chromosomes and the male has one X and one Y. What are the genotypes of the parents? A wewe and wY B wew and wY C wew+ and wY D wew and w+Y E wewe and w+Y
