Answer #1

Xw+Y × XwXw

Gametes Xw
Xw+ Xw+Xw (red eyed female)
Y XwY (white eyed male)

Out of 2 progenies, 1 is female and 1 is male.

Out of 2 progenies, 1 is red eyed and 1 is white eyed.

Phenotypic ratio -

Red eyed male = 0

White eyed male = 50%

Red eyed female = 50%

White eyed male = 0

Genotypic ratio -

Xw+Y = 0

XwY = 50

Xw+Xw+ = 0

Xw+Xw = 50

XwXw = 0
