Answer:
The answer is 25%.
Explanation:
Hemophilia is a recessive illness that is x-linked.
If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.
Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.
The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.
So the probability that their first child will be a son with hemophilia is 25%.
