<u><em>XRY</em></u> X <em><u>XR Xr</u></em>
<em><u>the gametes from the male Drosophila are XR and Y</u></em>
<em><u>the gametes from the female Drosophila re XR and Xr</u></em>
<em><u></u></em>
<em><u></u></em>
from this punnet square we can se that the genotype ratio
XRXR:XRY:XRXr:XrY is 1:1:1:1
The phenotype ratio:
red eyed female:red eyed male:white eyed male is 2:1:1
