Answer:

XHXH

Explanation:

Hemophilia is an inherited genetic disorder that affects the body's ability to manufacture blood clots, which is a necessary step to prevent bleeding. Hemophilia A and B are both X-linked recessive illnesses, although females are not affected. X-linked recessive inheritance is a kind of inheritance in which a mutation in an X-chromosome gene causes the phenotype to be manifested in males who are hemizygous for the gene mutation because they have one X and one Y chromosome.
