Use the following information to answer the questions below.
Drosophila (fruit flies) usually have long wings (+) but mutations in two different genes can result in bent wings (bt) or vestigial wings (vg).
-If a homozygous bent wing fly is mated with a homozygous vestigial wing fly, which of the following offspring would you expect?
A) all +bt +vg heterozygotes
B) 1/2 bent and 1/2 vestigial flies
C) all homozygous + flies
D) 3/4 bent to 1/4 vestigial ratio
E) 1/2 bent and vestigial to 1/2 normal

Since the genes for bent wings and vestigial wings are on different loci, mating homozygous bent wing flies with homozygous vestigial wing flies would result in offspring that are heterozygous for both traits, thus all +bt +vg heterozygotes.
