The correct answer is XHXH.

Hemophilia is an inherited genetic disease, which damages the tendency of the body to produce blood clots, that is, a procedure required to inhibit bleeding. Hemophilia A and B are both X-linked recessive disorders, though the females are hardly influenced.

X-linked recessive inheritance refers to a kind of inheritance in which a mutation in a gene on the X-chromosome makes the phenotype to be articulated in males hemizygous for the mutation of the gene, as they exhibit one X and one Y chromosome.
