Question

You are conducting independent research for your Honors Thesis in a Drosophila research lab. One of the graduate student researchers has provided you with two mutant strains of Drosophila. One has scarlet eyes, and the other has brown eyes. You cross homozygous scarlet-eyed male Drosophila with female flies homozygous for the brown-eye color allele, and all of the male and female F₁ flies have wild-type eyes. Crosses involving F₁ males x F₁ females yield the results shown below. You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results.

A) Please define the alleles represented in this cross.

B) List the genotypes of all classes of individuals in the P, F₁, and F₂Be sure to use the alleles you defined in Part A
