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 expect to find them?

The F1 flies are heterozygous for both traits (Vgvg Hh). In the F2 generation, a 9:3:3:1 phenotypic ratio is expected for a dihybrid cross with independent assortment. This translates to 576 wild, 192 vestigial, 192 hairy, and 64 vestigial hairy out of 1024 flies.
