QUESTION 4 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 vhite eyes, wild-type wings 142 vhite eyes, miniature wings 414 Vhat is the genetic distance between these two loci? О 25сМ О 33.3сМ 44.4cM 10.8cM OThese loci are not linked so they are 50CM apart.

QUESTION 4
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?
O 25CM
33.3cM
O 44.4cM
O 10.8cM
O These loci are not linked so they are 50CM apart.
