You cross a p+/v+ p+/v+ male drosophila to a p-/v- p-/v- and obtain the F1 hybrid. Now you cross the F1 male with double recessive female. What will be the recombination phenotype in F2?

(a) p+/v+ p-/v- only

(b) p+/v+ p-/v- and p-/v- p-/v-

(c) p+/v+ p-/v- and p-/v- p-/v- also p+/v- p-/v- and p-/v- p-/v-

(d) p+/v+ p-/v- and p-/v- p-/v- also p-/v+ p-/v- and p-/v- p-/v-

The question was posed to me in quiz.
