An inherited disorder where the body is unable to produce one or more factors essential for blood clotting (most notably Factor 8). A sufferer will bruise very easily and bleed profusely if cut or injured.
The mutant gene responsible is carried on the X Chromosome. As males only have one copy of the X Chromosome they suffer from this condition. In most circumstances females will have the mutation on one X Chromosome and not the other so they will be carriers but not sufferers. Female "double X" sufferers are not usually born alive.
The classic example of hereditary haemophilia is in the British Royal Family descending from Queen Victoria
