an F2 generation. If there are a total of 200 F2 flies, how many of the F2 females are expected to have short bristles? a) 0 b) 50 c) 75 d) 100 e) 150 Wild type fruit flies have grey bodies and straight wings. Yellow bodies and curly wings are both recessive phenotypes. The body color gene is X-linked; the wild type allele is designated XY+. The wing shape gene is autosomal; the wild type allele is designated C+. You cross a pure breeding yellow-bodied, curly-winged female with a grey-bodied, straight-winged male to produce an F1 generation. Use this information to answer questions X-Y below. You cross two F1 flies to produce an F2 generation. What proportion of the F2 female flies are expected to have curly wings and yellow bodies? a) 1/16 b) 1/4 c) 1/8 d) 3/8 e) 3/16
