The X and Y chromosomes are called sex chromosomes. The gene for hemophilia is carried on the X chromosome. Hemophilia is inherited in an X-linked recessive manner. Females inherit two X chromosomes, one from their mother and one from their father (XX). Males inherit an X chromosome from their mother and a Y chromosome from their father (XY).
Hemophilia A and B are more common in males than females because of the genetic transmission. Hemophilia C is an autosomal inherited form of the disease, meaning that it affects males and females equally. This is because the genetic defect that causes this type of hemophilia is not related to sex chromosomes.
