hi.....here is your answer.

Why hemophilia is more rare in females?

Hemophilia being a sex chromosome related recessive disorder has its gene present on X chromosome. Since males have one X and one Y chromosome, and the genes present on X don't have counter genes on Y, only one affected gene(to be present on X) is required for the disease in males. While in females, there are 2 X chromosomes. For the disease to occur both the X chromosomes should have the affected genes which is a rare chance. For this to be possible, the father of the female must be diseased while the mother must atleast be a carrier.
