A wild-type fruit fly (heterozygous for gray body and normal wings) is mated with a black fly with vestigial wings. The offspring have the following phenotypic distribution? 778 wild type, 785 black-vestigial, 158 black-normal, 162 gray-vestigial. What is the recombination frequency between these genes for body color and wing size?
In another cross, a wild-type fruit fly (heterozygous for gray body color and red eyes) was mated with a black fruit fly with purple eyes. The offspring were as follows: wild type = 721; black-purple = 751; gray-purple = 49; black-red = 45. What is the recombination frequency between these genes for body color and eye color? How many map units apart are the genes for body color and eye color?
