For example, an X-linked recessive allele in humans causes haemophilia , which is much more common in males than females because males are hemizygous see zygosity and therefore express the trait when they inherit one mutant allele. Sickle cell anemia is a red blood cell disorder. Carrier females have about half the usual amount of coagulation factor VIII or coagulation factor IX, which is generally enough for normal blood clotting.
