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%.
I hope this answer helps.
Answer:
Autosomal dominant pattern.
Explanation:
If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.
