The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h ) body. Assume that a cross is made between a fly with normal wings (homozygous) and a hairy body and a fly with vestigial wings and normal body hair (homozygous). The wild-type F1 flies were crossed among each other to produce 1024 offspring. How many of the F2 flies would you expect to have normal wings and a hairy body?

A cross was made between homozygous wild-type female Drosophila and yellow-bodied male Drosophila. All of the resulting offspring were phenotypically wild type. Offspring of the F2 generation had the following phenotypes:         Sex               Phenotype           Number         male                wild                     96       male              yellow                   99       female             wild                   197   Would you expect to get a similar result if you had originally crossed a yellow-bodied female with a wild-type male?
