Cinnabar eyes (e), smooth abdomen (a) and curved wings (w) a…
Cinnabar eyes (e), smooth abdomen (a) and curved wings (w) are all genes linked to chromosome 2 of Drosophila. These mutant alleles are all recessive to the wild-type alleles. A female heterozygous for the mutant alleles at each locus is crossed to a homozygous recessive male. They have these progeny: Phenotype Number Cinnabar, normal abdomen normal wings 300 Wild type 50 Cinnabar, smooth abdomen, curved wings 45 Cinnabar, normal abdomen, curved wings 10 Wild-type eyes, normal abdomen, curved wings 150 Wild-type eyes, smooth abdomen, curved wings 308 Cinnabar, smooth abdomen, normal wings 125 Wild-type eyes, smooth abdomen, normal wings 12 Total = 1000 What are the three map distances between cinnabar eye (e), smooth abdomen (a) and curved wing (w)?
