Question

In fruit flies, red eyes (pr+_) are dominant to purple eyes (prpr) and normal wings (vg+_) are dominant to vestigial wings (vgvg). The genes are located on the same chromosome. A purebreeding red-eyed fly with vestigial wings was crossed with a pure-breeding purple-eyed fly with normal wings. All of the F1 progeny had a WT phenotype. The recombination frequency between the two genes is 10%. If an F1 individual was test crossed, what percentage of the progeny would you expect to have the WT phenotype?

A. 50%
B. 10%
C. 90%
D. 5%
E. 95%

Answer 1

90%

Step-by-step explanation:

Between the two gene the on with red eyes and vestigial wings will be 90%
