Why Hemophilia more common in male than in female?
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 allele for hemophilia is on the x chromosomes and is a?
Sex-linked genes
What chromosomes has been determined to carry this gene in hemophilia?
the X chromosome

Which chromosome contains the gene for 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.
What is a carrier for hemophilia?
A carrier for hemophilia is a female who carries the genetic mutation for hemophilia on one of her X chromosomes, but does not exhibit symptoms of the condition herself. Carriers can pass on the gene mutation to their children, resulting in hemophilia in male offspring. Testing can confirm carrier status.
The hereditary disease in which clotting does not occur is known as?
hemophilia
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
What do you get when you cross a male hemophiliac with a female hemophiliac?
The gene for hemophilia A is found on the X chromosome (it is a sex-linked recessive disorder). Women have two X chromosomes and men have one X chromosome. A woman with hemophilia (very rare) would have the mutated gene on both of her X chromosomes. This means that all of their children, both male and female would have hemophilia.
Why are men most likely to have hemophilia?
Since Hemophilia A is an "X Chromosome" disease and women have two "X" Chromosomes, women with only one "X" Chromosome with the disorder would be carriers of the disease but not affected by it. Women with both "X" Chromosomes with the disorder would be very rare.
If you know a woman has hemophilia what can you infer about her parents genetype?
If a woman has hemophilia, it means she inherited one affected X chromosome from each of her parents. This suggests that her father is likely a carrier of the hemophilia gene on his X chromosome, and her mother is either a carrier of the gene on one of her X chromosomes or has hemophilia herself.
Why is colorblindness or hemophilla more common in males than females?
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.
