What allele is passed to a offspring male if mother has hemophilia?
Hemophilia is typically an X-linked recessive condition. If a mother has hemophilia, she carries two copies of the hemophilia allele on her X chromosomes (since females have two X chromosomes). Therefore, any male offspring will inherit one of her X chromosomes, which will carry the hemophilia allele, leading to him being affected by the condition. The male will inherit his Y chromosome from his father, which does not carry the hemophilia gene.
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
Why is hemophilia more common in males than in females?
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.

Since it is unlikely that females will have 2 altered copies of this gene it is therefor very rare for females to have hemophilia.
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?
Does having too many chromosomes result in hemophilia?
No, hemophilia is not caused by having too many chromosomes. It is a genetic disorder primarily linked to mutations in specific genes responsible for blood clotting, particularly the F8 gene (hemophilia A) or the F9 gene (hemophilia B), both located on the X chromosome. Hemophilia is typically inherited in an X-linked recessive manner, meaning it mainly affects males while females can be carriers. Chromosomal abnormalities, such as having an extra chromosome, do not directly cause hemophilia.
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.
