Assume the genotype of white eye female fruit fly is XwXw, and the genotype (Xw+Y) is for red eye male fruit fly. How do you verify these two genotypes?

Answer #1

We can verify these genotypes by providing the mating condition to these fruit flies. Then observed for the progenies.

Parents: XwXw ( white eye female) × Xw+Y ( Red eye female)

Punnet square:

Gametes Xw+ Y
Xw Xw+Xw ( red eye daughter) XwY ( white eye son)
Xw Xw+Xw ( red eyed daughter) XwY ( white eye son)

If we get all red eyed daughters and white eye son in the progenies of these two parents mating, then the genotype of male parent is Xw+Y and the female parent is XwXw.

The number of facets in the eye of the fruit fly Drosophila melanogaster is of interest in genetics to model changes across many generations (ie genetic selection).
