Why do women almost never get hemophilia?

Hemophilia is a dangerous disease that affects only men. Associated with a bleeding disorder, any scratch can lead to bleeding. The hemophilia gene is located on the X chromosome, it happens:
– Dominant (blood clotting normally).
– Recessive (the gene that determines its non-coagulation).
Women, being carriers of a recessive gene in one of their chromosomes, do not know about this, since the dominant hemophilia gene in the other X chromosome suppresses the recessive gene.
If the X chromosome with the hemophilia gene goes to a man, which he can only receive from the mother, the carrier of this gene. The man will become hemophilic, since the man has only one X chromosome, and the Y chromosome does not have a blood coagulation gene.
It is impossible to inherit the hemophilia gene from the father, provided that the mother is not a carrier.
Women with hemophilia are very rare. This mutation can only be caused by family marriages.
