1. Ebony (black body, e) and apterous (vestigial wings, vg) are recessive traits, present on different chromosomes. An ebony female with wild-type wings (whose parents were true breeding for wild-type wings) is crossed with an apterous male with wild-type (brown) body color (whose parents were true breeding for wild-type body color).
a. What are the genotypes of the parental flies?
b. List the genotype(s) and phenotype(s) you expect to see in the F1 offspring. Explain how you arrived at your answer.
