Q1. In Drosophila melanogaster, vestigial (short) wings (vg) are caused by a recessive allele of a gene that independently assorts with a gene pair that influences body hair. Hairy (h) results in a hairy body. A cross is made between a fly with normal (wild) wings and a hairy body and a fly with vestigial wings and a normal (wild) body. The phenotypically normal F1 flies were crossed among each other, and 1024 F2 flies were reared. What phenotypes would you expect in the F2, and in what actual numbers (not ratios) would you be expecting to find them?
