In fruit flies, white eyes (we) and miniature wings (mw) are encoded by two mutant alleles that are recessive to those that produce wild- type traits (we+ and mw+); these two genes are on the same chromosome. A fly homozygous for white eyes and miniature wings is crossed with a fly homozygous for the wild-type traits. The F1 have normal eyes and normal wings. The F1 are crossed with flies that have white eyes and miniature wings in a testcross. The progeny of this testcross are (1000 total): wild-type eyes, wild-type wings 336 wild-type eyes, miniature wings 108 white eyes, wild-type wings 142 white eyes, miniature wings 414 What is the genetic distance between these two loci? 25CM 33.3cM 44.4CM 10,8CM These loci are not linked so they are 50cm apart.
