The gene for hemophilia is carried on the X chromosome. A male has one X and one Y. Since the trait is recessive it would be easier for a male to get a recssive allele, rather than a female get two recessive alleles.
Hemophilia is a sex linked genetic disorder where the defective gene is located on an X chromosome.
Women have two X chromosomes while men have one X chromosome and one Y chromosome.
Thus women have a spare X chromosome which 'backs up' for one which may carry the defect.
However if men inherit a faulty X chromosome from their mother, they will definitely get the disease and this is why the disorder is almost entirely manifested in males.
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.
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.
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.
Pericarditis is more common in males than females with a ratio of seven to three
It is an X-linked genetic disorder. Since males are XY and females are XX, it is a higher possibility that either parent is carrying the hemophilia allele which affects the X in either male / female or both.
Males only have one copy of the X chromosome
Because the gene that causes hemophilia is located on the X chromosome, so it will occur in males more frequently than in females.
Because males have the chromosome XY. And Hemophilia attacks the X chromosomes, so if the disorder gets to the X chromosome of the male, it doesnt have another X chromosome to back it up like females do.(XX)
