to the point of being functionless. Assume this is a system of complete
dominance. In a cross between two fruit flies that are both heterozygous
for the wing length allele, what are the expected genotypes? (0.5 point)
a. 75% long wings, 25% vestigial wings
b. 25% long wings, 50% intermediate wings, 25% vestigial wings
c. 50% homozygous dominant, 50% homozygous recessive
