1 Carrier female to female progeny
2 Father to son
3 Carrier female to male progeny
4 Father to son and daughter

If mother is a carrier for colour blindness and father is normal, then in the offsprings this disease may be seen in
1 50 % sons and 50 % daughters (carriers)
2 All the sons and not in daughters
3 All the daughters
4 All the sons
Explanation:
If a normal female (carrier ) marries a normal male, the possibilities are: there is 50 % chance that they are carriers due to defective X chromosome of the mother. And there is 50% chance for the son to be colourblind. Therefore, the carrier mother is heterogametic for recessive colour blindness gene.

If a man and a woman both having colour blind fathers marry, the percentage probability of their first daughter to be colour blind is:
1 \(25\% \)
2 \(0\% \)
3 \(100\% \)
4 \(50\% \)
Explanation:
0 percent as the father is normal and mother is a carrier.
