Vedclass · Answer

(D) Haemophilia is a sex-linked recessive disorder in which the blood fails to clot normally.It is caused by a defect in the genes that code for clotting factors (specifically Factor $VIII$ or $IX$).Because of this genetic defect,the individual lacks the necessary proteins required for the blood coagulation cascade.Consequently,even a minor injury can lead to excessive and continuous bleeding,as the clotting mechanism is significantly impaired or fails to initiate properly.Therefore,the most accurate description is that there is a failure in the clotting mechanism of blood.
