TION S
ebody color (e) is recessive to wildtype body color (e*) and curled wings (cu) is recessive to wildtype straight wings (cu*). The ebony and curled genes are both located on chromosome 3 and the distance between the two genes is 18 m.u. The recessive allele (bw) leads to flies with brown colored eyes and the dominant wildtype allele (bw*) leads to flies with red eyes. Fill in the expected proportions of progeny for each phenotypic group when a female heterozygous fly of the genotype given below is tested crossed to a homozygous recessive male fly.
