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%
