Why are women carriers for the disease hemophilia?

Answer 1

Women can, in fact, suffer from haemophilia, but it is more rare in women, as it is a recessive, sex-linked X chromosome disorder, so in order to manifest the disease, a woman would need two copies of the defective gene, while men need only one. Thus it is guaranteed to manifest in a man who carries the gene, but not in a woman unless she receives the gene from both parents.

Answer 2

They can, but it is very rare. Quote from the Related Link:

Men and women each have 23 pairs of chromosomes (pronounced: kro-muh-soamz). Women have two X chromosomes; men have one X and one Y chromosome. Hemophilia is an X-linked genetic disorder, which means that it's passed from mother to son on the X chromosome. If the mother carries the gene for hemophilia on one of her X chromosomes, each of her sons will have a 50% chance of having hemophilia. Although girls rarely develop the symptoms of hemophilia itself, they can be carriers of the disease. For a girl to get hemophilia, she would have to receive the disease on the chromosome she receives from her father, who would have hemophilia, as well as from the X chromosome of her mother, who would be a carrier. Although this is not impossible, it is highly unlikely.

Answer 3

Because hemophilia is associated to the X-chromosomes, which means to the women's chromosomes.

Answer 4

Girls can get hemophilia, but it's much less common than in boys because girls need two copies of the defective gene in order to get it whereas boys will be hemophiliacs with just one.
