Genes a and b are located close together in the same chromosome. Allele A for long wings is completely dominant to allele a for short wings. Allele B for light body color is completely dominant to allele b for dark body color. A female fly is heterozygous for both genes such that alleles A and b are present in one homolog, whereas alleles a and B are present in the other homolog. If she is crossed with a male fly that is homozygous recessive for both genes, then the majority of their progeny would:
A) have long wings and a light body or short wings and a dark body.
B) have long wings and a light body or long wings and a dark body.
C) have short wings and a light body or long wings and a dark body.
D) have short wings and a light body or long wings and a light body.
E) look just like their mother.
