First of all, we need to do the Punnet square to determine what will be the offspring genotype:
As we can see on the Punnet square, we have 4 different possible genotypes for the offspring, and in this case in particular, each genotype corresponds to a specific phenotype too, because this characteristic is linked to a sex chromosome.
We then have half the offspring blind, but half of it are women (25% out of the total offspring) and a half are men.
Also, we have the other half of the offspring not blind, with half of it being women and the other half being men.
