Answer:
Hemophilia
Step-by-step explanation:
This is a disorder in which a blood coagulation factor is missing from the blood, so if the person with the disorder gets even a small injury, he'll bleed a lot due to absence of proper blood coagulation.
It's more common in males than females because females have two X chromosomes. If they have one recessive allelle on one X chromosome, while the other has the dominant allele, they're going to be asyptomatic carriers of the recessive allele.
However, since males have only one X chromosome, having the recessive allele means that they'll suffer from hemophilia. There's no chance of them being just carriers unlike the females.
