Haemophilia is a disease that is inherited through the sex chromosomes is True.

Haemophilia is a sex-linked bleeding disorder that is inherited through sex chromosomes during gene mutations. The disease causes certain essential proteins termed as coagulation factors, which are formed in a human body, to be produced in an abnormal way and less in amount.

These proteins are to work together in timely execution of blood clotting process in case of an injury or wound. Weak presence of coagulation proteins in patient's blood cannot help in speedy recovery of the damaged blood vessels and hence the patient bleeds continuously for a longer period. The wound will be slow to recover and at times the bleeding can become difficult to be controlled.
