which of the following statements are true about hemophilia?
it is an example of an autosomal dominant disorder.
it is an example of an autosomal recessive disorder.
it is an example of a sex-linked disorder.
it involves a protein inside the red blood cells.
it is a disease in which a person has trouble stopping bleeding.

Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.

Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.

Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
