Genetic Experiments by Thomas Hunt Morgan and Colleagues Examined Eye

question 15

Short Answer

Genetic experiments by Thomas Hunt Morgan and colleagues examined eye color in Drosophila fruit flies. Males are XY and females are XX, and the gene responsible for eye color is on the X chromosome. Red eye color (wild-type) is dominant to white eye color (mutant). The wild type allele is denoted X^w+ and the mutant allele is X^w. Match the missing values in the following sentence:
In a cross between a homozygous female and a red-eye male, [A] of the male offspring will have the same phenotype and [B] of the female offspring will have white eyes. In a cross between a heterozygous female and a white-eye male, [C] of the female offspring will have white eyes and [D] of the offspring will be red-eye males.
