Haemophilia results from the mutation of the genes
Answer Details
Haemophilia results from the mutation of the genes which control the mechanism for blood-clotting. Haemophilia is a genetic disorder that affects the blood's ability to clot. It is caused by a mutation in one of the genes that are responsible for making clotting factors in the blood. These genes are located on the X chromosome, which means that haemophilia is more common in males since they only have one X chromosome. Females have two X chromosomes, and if one is affected, the other can compensate for the mutation. When a person with haemophilia is injured, their blood does not clot correctly, leading to prolonged bleeding and bruising. There are different types of haemophilia, depending on which clotting factor is affected, and the severity of the disorder can also vary. Overall, haemophilia is a genetic disorder that is caused by a mutation in the genes that control the mechanism for blood-clotting.
