Person whose father is colourblind marries a lady whose mother is daughter of a colourblind man. Their children will be
1 All normal
2 All colourblind
3 All sons colourblind
4 Some sons normal and some colourblind
Explanation:
The person whose father is colour blind is normal because the colour blind genes located on X- chromosome of father gets transferred into his daughters only and not to the son. This son marries a woman whose mother is daughter of colour blind man that is woman is carrier for colour blind. Hence, normal man marries a carrier woman and as a result some of their sons will be normal and some colour blind.

A colour-blind man marries the daughter of another colour-blind man whose wife had a normal genotype for colour vision. IN their progeny:
1 All the children would colour-blind
2 All their sons are colour-blind
3 None of the daughters would be colour-blind
4 Half of their sons and half of their daughters would be colour- blind
Explanation:
The daughter of a colour-blind man\(\left(\mathrm{X}^{\mathrm{C}} \mathrm{Y}\right)\) whose wife had a normal genotype \({\rm{(X Y)}}\) for colour vision would have \(\left(\mathrm{X}^{\mathrm{C}} \mathrm{Y}\right)\) genotype. On marrying a colour-blind man \(\left(\mathrm{X}^{\mathrm{C}} \mathrm{Y}\right)\). They children are expected to have: Thus, half of their sons and half of their daughters will be colour-blind.
