KCET 2018 Biology Solved Paper

The male’s father was colour blind with genotype XcY and mother had no gene for colour blindness with genotype XX, thus genotype of male would be
Xc‌Y×XX
XY
The female’s father was also colour blind with genotype XcY and mother had no gene for colour blindness, thus with genotype XX, thus genotype of female would be
Xc‌Y×XX
XXc
On crossing this male and female:
XY×XcX
Their daughter can have genotype XX or XXc, thus she could be normal or carrier, but the probability of she being colour blind is 0%.
