Question

Quizplus · Accepted Answer

Hemophilia is caused by a deficiency in the blood clotting protein factors VIII or IX, which are located on the X chromosome. Since males only have one X chromosome, they are more likely to inherit and have symptoms of hemophilia than females. Hemophilia does not cause sterility and it is inherited on a sex chromosome, not autosomes.
