In fruit flies, the white eye allele is X-linked and recessive. The wildtype, dominant eye color is red. If a male with white eyes is crossed to a female that is a carrier of the white eye allele (but has the red eye phenotype), and they produce 64 offspring flies, how many white eye females would you predict to have? Enter just the number of flies. You do not need to consider any effect of the white eye allele on survival, assume all flies survive equally.
Joanna Q.
Eye color in certain species is controlled by genes. The gene for white eyes in flies is denoted as "e", while the gene for red eyes is denoted as "E". A single pair of flies, both of which had red eyes, were crossed with flies that had white eyes. The male and female offspring from this cross were also red-eyed. The question is whether the gene for red eyes or the gene for white eyes is dominant. Additionally, the genotype of the white-eyed parents and the genotype(s) of the red-eyed offspring need to be determined. If one of the red-eyed offspring is mated with the white-eyed parent, the expected ratio of offspring with respect to eye color needs to be determined.

Red eyes are dominant on fruit flies but an x-linked recessive allele will produce white eyed flies. If a red eyed female mates with a white eyed male, what is the probability of white eyes in the F1 generation?
