4. Cause of the hemophilia  Hemophilia (A) is caused by a mutation in the gene for factor VIII, there is deficiency of this clotting factor. Hemophilia is an inherited genetic condition and that’s simple to understand it way passed down through families. It is caused by a weakness in the gene that controls how the body makes blood-clotting factors (Vlll) These genes are located on the X chromosome, making hemophilia an X-linked recessive disorder. This disorder is a mutation because it does cause a change which is the blood clotting factors.

5. How the hemophilia is inherited  Hemophilia (A) is inherited in an X linked recessive pattern.

However, There are also a lot of medication that is recommended by the doctors such as pills and vaccines.

7. How the hemophilia is diagnosed  Screening tests and clotting factor tests are the best way to diagnosis. Screening tests are blood tests that show if the blood is clotting properly. Clotting factor tests are also known as factor assays, they required diagnosing a bleeding disorder.

8. How many and what type of people are likely to have the hemophilia  The forms of hemophilia occur much more commonly in men more then women. Hemophilia A is the most common type of the condition it is 1 in 4,000 to 1 in 5,000 males worldwide are born with this disorder.
