Question

The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by an autosomal recessive mutant allele that independently assorts with an autosomal recessive mutant allele for hairy (h) body. A parental cross was made between a fly that is homozygous for normal wings with a hairy body and a fly with vestigial wings that is homozygous for normal body hair. The wild-type F1 flies were crossed to each other and produced 1536 offspring. The phenotypes of the F2 offspring exhibited a 9:3:3:1 ratio.

Which phenotypes would you expect among the 1536 offspring of the F2 generation?

How many of each phenotype of the F2 generation flies would you expect
