Unformatted text preview: epistatic to cinnabar, so cn cn; w w flies have white eyes. A wild-type female of genotype cn + cn ; w + w is crossed to a cn + cn ; w Y white eyed male. What progeny ratios for eye color will be produced among the male and female offspring? Note: The wild-type allele of each gene is dominant only to its own mutant allele. Epistasis is NOT a form of dominance. For recessive alleles, the “covering up” or “masking” of the phenotype that is called epistasis only occurs when both genes are in the homozygous recessive condition. Be careful to clarify your thinking about the difference between epistasis and dominance. Epistasis will not be defined on the exam....
