XR Y

Xr XRXr XrY

Explanation:

Hello!

r: recessive white allele

R: dominant red allele

XX: female

XY: male

XrXr: white-eyed female. A possible gamete Xr (

assuming a homozygous female)

XRY: red-eyed male. Possible XR and Y alleles.

50% of the offspring will be heterozygous female with red-eye phenotype (dominant)

50% of the offspring will be male with white eyes phenotype (recessive).
