When two mutant flies having white eyes were crossed, all of the offspring showed wild type red eyes. How is this possible? The parents carried mutations on different but complementary genes whose products are both required for the red eye phenotype. The parents carried different mutations on the same gene whose product is required for the red eye phenotype. The parents carry recessive lethal mutations that affect the survival of the white-eyed flies among the offspring. The red eye phenotype is recessive to the white eye phenotype, which is why the red eye only appears in the F1 generation. The white eye allele shows dominant epistasis over the red eye allele.
