Is Haemophilia A Sex Linked Disease? How?
Yes,The gene for Haemophilia is carried on the X sex chromosome (females are XX; males are XY). A man with Haemophilia passes the faulty gene to his daughters who then carry this gene and may pass the condition onto their sons. A man with Haemophilia does not pass the faulty gene onto his sons because they receive a copy of his Y chromosome (their X chromosome comes from the mother).
