Rationale: Males inherit hemophilia from their mothers, and females inherit the carrier status from their fathers. Some females who are carriers have an increased tendency to bleed, and, alt-hough it is rare, females can have hemophilia if their fathers have the disorder and their mothers are carriers of the genetic disorder. Hemophilia is inherited in a recessive manner via a genetic defect on the X chromosome. Hemophilia A results from a deficiency of factor VIII. Hemophilia B (Christmas disease) is a deficiency of factor IX.
