Why Are males more often hemophiliac?

Answer 1

Hemophilia is a recessive, sex-linked, X chromosome disorder. It would have to be present on both X chromosomes to present in females. It only has to be present on the single X chromosome to present in males.

Answer 2

Because hemophila is carried on the X chromosome. Usually a recessive disease requires both chromosomes to have the bad gene. Males only have one X chromosome, and the Y chromosome can't mask the Recessive gene on the X, So men With the Gene will Hve the disease.

Answer 3

Since a woman has two X chromosomes, even if one is infected with hemophilia, the other most likely will not be and

will still be able to produce the proteins needed for the blood to clot. To have hemophilia, the woman would have

had to acquire an infected X chromosome from both her mother and her father.

Answer 4

It is a sex-linked recessive disease, meaning that a girl would need two copies of the affected gene to have the disease, but a boy only needs one copy.

H = normal, h = haemophilia:

Girl - XHXh - normal phenotype

Boy - XhY - haemophilia

Answer 5

The gene that carries the colorblindness is on the X chromosome. Because of that, males have a better chance of getting it because they only have one X chromosome.

Answer 6

The reason why there are more male hemophiliacs than female, is because menstruation is fatal to a hemophiliac, which limits the survival of female hemophiliacs.

Answer 7

Because the X is recessive linked
