Is the trait sex-linked or autosomal

Reference no: EM13530121

A new student of genetics suspects that a particularrecessive trait in fruit flies (dumpy wings, which are somewhat smaller and more bell-shaped than thewild type) is sex-linked. A single mating between a fly with dumpy wings (dp; female) and a flywith wild-type wings (Dp; male) produces three dumpy-winged females and two wild-type malesin the F1 generation. On the basis of these data, is the trait sex-linked or autosomal? Whatwere the genotypes of the parents? Explain how these conclusions can be reached on the basisof so few data
