Sex-Linked Inheritance Problem Set
Problem 1: Crossing a white-eyed female and red-eyed male fly
In a cross between a white-eyed female fruit fly and red-eyed male, what percent of the female offspring will have white eyes? (White eyes are X-linked, recessive)
All of the females are red-eyed and heterozygous. All of the males are white-eyed and hemizygous.
