Hemophilia

Hemophilia is a sex-linked genetic disease in which the body’s ability to control bleeding is impaired due to the absence or abnormality of a clotting factor in the blood. The two most common forms of the disease are caused by a genetic defect present on the X chromosome. Because females have two X chromosomes, whereas males have only one, females are more commonly carriers of the recessive disease while males tend to be the hemophiliacs. Why is hemophilia also called “the royal disease”? Discuss
