In fruit flies, the dominant V allele produces long wings, whereas the recessive v allele produces vestigial wings - that is, wings reduced in size 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?

a.) 75% long wings, 25% vestigial wings

b.) 25% long wings, 50% intermediate wings, 25% vestigial wings

c.) 50% homozygous dominant, 50% homozygous recessive

d.) 25% homozygous dominant, 50% heterozygous, 25% homozygous recessive
