In Drosophila, vestigial (partially formed) wings (vg) arerecessive to normal long wings (vg+), and the gene for this traitis located on an autosome. The gene for the white-eye trait is onthe X chromosome. Suppose a homozygous white-eyed, long-wingedfemale fly is crossed with a homozygous red-eyed, vestigial wingedmale.
. What are the expected genotypes, phenotypes and their ratiosin the F1 flies?
P1 white, long females: ______________ X P2 red, vestigialmales: ___________________
F1 genotypes:_______________________________________________________________
F1 phenotypes:_______________________________________________________________
2. What are the expected genotypes, phenotypes and their ratiosin the F2 flies?
F1 females: _____________________ X F1 males:__________________________
3. What are the expected genotypes and phenotypes, and theratios of each of the progeny resulting from a cross between F1flies back to each parent?
F1 female: _____________________ X P2 red, vestigial male:__________________________
F1 male: _____________________ X P1 white, long female:__________________________
