In Drosophila melanogaster there is a sex-linked gene for eye color that is found only on the X
chromosome. The allele for red eye color (Xw+) is dominant over the allele for white eye color (Xw). You examine a vial of 100 flies that are all offspring from a single genetic cross. You find only redeyed females and red-eyed males present. Flies from the vial were allowed to interbreed, and in the next generation you find only red-eyed females, but you find both red-eyed and white-eyed males. The genotypes of the original parents were
a. Xw+Xw+; XwY. b. Xw+Xw; XwY. c. XwXw; Xw+Y. d. Xw+Xw; Xw+Y. e. XwXw; XwY.
