Hemophilia is a genetic condition. This genetic condition is carried on the X chromosome in women. A women is a carrier when her father has hemophilia or when her mother is a carrier and she receives the X that has hemophilia. There are tests available to be tested if you think you may be a carrier, check with your doctor.
There also is mutation of the gene, that is when it shows up out of now where.
I know that some of you carriers out there may have many questions, and feelings that you might want to share.
