this disease is caused by a recessive allele that is found only on the x chromosome. a human female has two x chromosomes. a human male only has 1 x chromosome. therefore, a male needs only one recessives allele to have hemophilia, while a female needs two recessive allele. as a result, hemophilia is much more common in males.
Hemophilia
It is more common in men.
Hemophilia is more common in males. It's a sex-linked disease.
Yes. Hemophilia is sex-linked, and is much more common in males than in females, but it is not impossible for a girl to have hemophilia.
Males.
The X chromosome. That's why it's more common in males; females have 2 X chromosomes, but males only have 1. So if a woman has the hemophilia mutation on one of her chromosomes, she probably won't be affected by it.
Men Have XY chromosomes. women have XX chromosomes. To get Hemophilia, all of your X chromosomes have to be affected. as you can see, it is much easier for a man to get it than a woman.
Females have shorter urethras than males.
Males only have one copy of the X chromosome
The genes associated with Hemophilia A and B are located on the X chromosome, which is one of the 2 sex chromosomes. For males, who have only 1 X chromosome, 1 altered copy of the gene in each cell is sufficient to cause hemophilia. In females, who have 2 X chromosomes, a mutation would have to occur in both copies of the gene to cause hemophilia. Since it is unlikely that females will have 2 altered copies of this gene it is therefor very rare for females to have hemophilia.
Hemophilia A affects between one in 5,000 to one in 10,000 males in most populations. Hemophilia B occurs in one in 40,000 to 50,000. The prevalence of hemophilia is estimated to be 13.4 cases per 100,000 U.S. males (10.5 hemophilia A and 2.9 hemophilia B). By race/ethnicity, the prevalence is 13.2 cases in 100,000 among white males, 11.0 among African-American males, and 11.5 among Hispanic males. Hemophilia C occurs primarily among individuals of Jewish descent.For the source and more detailed information concerning this request, click on the related links section (Answers.com) indicated below this answer box.Hemophilia A affects between one in 5,000 to one in 10,000 males in most populations.
