What happens when a female who is normal marries a man who has hemophilia?
If she gets the X chromosome with the hemophilia gene, she will have hemophilia. A man who has hemophilia and a woman who is a carrier have: a 25% (one in four) chance of having a son with hemophilia. a 25% chance of having a son with normal blood clotting.
What are the chances that a carrier female for hemophilia and an affected male will have an affected hemophilia daughter?

Why can only females be carriers of haemophilia?
These disorders affect males more often than females because females have an additional X chromosome that acts as a “back-up.” Because males only have one X chromosome, any mutation in the factor VIII or IX gene will result in hemophilia.

Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain.
Can hemophilia be prevented?
Hemophilia is a genetic (inherited) disease and cannot be prevented. Genetic counseling, identification of carriers through molecular genetic testing, and prenatal diagnosis are available to help individuals understand their risk of having a child with hemophilia.
