Question

1. Male fruit flieswith short wings and dark body color are mated to wild type females(long wings andgray bodycolor). The short wing and dark body color mutations are bothrecessive. The wing shape gene is on a different chromosome fromthe body colorgene.

Assign letterdesignations to each gene and the alleles.Write outthe cross and the expected F1offspring.

If the F1 hybridfemale fruit flies are mated to males with short wings and darkbody color, what phenotypesand ratiosare expected in the F2 generation? (Hint: This is a testcross.)

2. Consider Mendel
