  1. If the carrier daughter mary a normal man 50% of their grand sons will become colour blind
    If carrier daughter marries a colour blind man 50% of their grand daughter will be carriers
    So in both the above cases, the result shows 50% of grand sons will be colour blind which in terms of over all progress (son+daughter) come as 25% thus confirming the probability as 0.25
