atids at the start of Meiosis I. If two chromosomes have similar positions, structures, and origins they are referred to as sister chromatids.

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

<h3><u>Explanation:</u></h3>

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.
