Is hemophilia a disorder

Answer 1

The clinical answer would be yes, however there are many exceptions to the rule in the case of hemophilia. The trait for hemophilia is carried on the X chromosome and is often recessive. This being the case, since females have 2 X chromosomes, there is typically a dominant gene on their other X that corrects the disorder if one X carries the trait for hemophilia.

Males, having only one X chromosome (paired with a Y chromosome) an only express the traits on the one X that they have. This being the case, a male with the trait for hemophilia on his X chromosome must be affected by it.

In more recent years it has become understood that the trait for hemophilia is not as recessive as once thought. In many females the trait has shown incomplete or shared dominance with the otherwise normal gene. This often results in the female having low clotting factor levels and actually being considered a mild or moderate hemophiliac.

Answer 2

Yes, hemophilia is an autosomal recessive disorder. Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern.

Answer 3

Yes, it's a genetic disorder. symptomatic chiefly in males, in which excessive bleeding occurs owing to the absence or abnormality of a clotting factor in the blood.
