What is the probability that a female child of Charles and Marie would suffer from hemophilia?

0 percent

25 percent

50 percent

100 percent

The correct option is A) zero percent

Explanation:

Hemophilia can be described as an X-linked recessive disorder in which the blood of a person is not able to clot properly. As it is a recessive disorder, both the alleles should be recessive for the disorder to occur. In males, as only one X chromosome is present hence, only one allele would be enough to cause the disorder in males. Whereas for females, both the X chromosomes will have to carry the recessive type alleles for the disorder to occur.
