The phenоtype оf vestigiаl (shоrt) wings (vg) in Drosophilа melаnogaster 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. What is the genotype of the F1 flies?
