Hemophilia is simply a disease that prevents blood from clotting properly. That being said a person who has this disorder will be bleed more than someone without hemophilia does. Hemophilia is an X-linked genetic recessive disorder, which means that it's passed down on the x chromosome. Each chromosome contains genes. On these genes, there are specific alleles which code for certain things. In the case of hemophilia having two copies of the recessive allele will make someone a hemophiliac. If someone has a dominant copy of the allele and recessive copy of the allele, this means that they would only be a carrier, meaning that they don't express symptoms of the disorder, however they can still have children with the disorder. If the person has two copies of the dominant allele, they will be completely free of hemophilia. In order for a female to get the condition they must have two copies of the recessive allele on the x chromosome. In order for a male to get hemophilia, they only need one copy of the recessive allele on the x chromosome. Because of this, it is much more likely for a male to get hemophilia than a female. This is the case with all disorders linked to the x chromosome.
