Because the mutated gene that causes this affliction in located on the X chromosome. It is recessive. That is why it affects more men than women. Men have this, XY, as their sex determinant and women have, XX, as their determinant. So, a recessive trait can be blocked by a dominant X in women but men have no such protection.

Is hemophilia a dominantrecessiv or a sex linked trait?
Sexlinked and recessive.
Why is hemophilia considered to be a sex trait?
It is carried on the X chromosome.
Is hemophilia A inherited as a recessive or dominant trait?
Hemophilia A is inherited as a recessive trait.
Is hemophilia a recessive or dominant trait?
Hemophelia is a recessive trait. By Aline Garcia
Is hemophilia recessive or dominant?
Hemophilia ia a sex linked disorder that is normally recessive. There are many cases however where trait shows "incomplete or shared" dominance. In these cases the females will have lowered percentages of the clotting factor proteins and may for all intents and purposes be considered mild or moderate hemophiliacs themselves.
Is sickle cell anemia a sexlinked trait?
Nope! The disease is equally in both males and females. This means that it is autosomal.
Example of sex-limited trait in animals?
Hemophilia.
What type of trait is hemophilia?
recessive sex-linked, X chromosome disorders, haemophilia is more likely to occur in males than females.
If both parents are carriers what will the child be?
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
Is hemophilia a disorder?
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.
Why is hemophilia considered to be a sex link trait?
Because the gene that causes hemophilia is located on the X chromosome, so it will occur in males more frequently than in females.
Is hemophilia a sex-limited or a sex-influenced trait?
Hemophilia, along with color blindness, is a sex-linked recessive trait. Hemophilia is when a person lacks a clotting factor in the blood. This results in the decreased ability to have blood clots. This can be dangerous because a person may internally or externally bleed to death. People with hemophilia must take clotting factors (by needle injection) frequently throughout their lives in order to live. As it is to be known, mothers are the carriers of these kind of traits. If a mother has the hemophilia trait, that means that her son will have hemophilia.
