Explanation / Answer

Albinism is X - linked recessive disorder. There is 100% of chance to produce an affected a male offspring and 50% of affected female and 50% of carrier females. Hence, the probability of 1 and 3 to be carriers is 50%.

The probability of any of the four children to be carriers is also 50%. This is because the out of 4, one son is affected and among other 3, 50% have chance of carrier and 25% to be unaffected.
