Question

What is not true of haemophilia?
A) Royal disease
B) Bleeder's disease
C) X-linked disease
D) Y-linked disease

Answer 1

Hint:It is one of the rarest blood disorders in the human body. The blood of hemophilia patients doesn't clot normally as it lacks an adequate amount of blood-clotting proteins. It is a genetic disorder.

Complete answer:
Haemophilia has been known as a royal disease as well. It is a disease that can transfer from one generation to another. This is on the grounds that the hemophilia gene was transferred from Queen Victoria, who had taken oath as a Queen of England in 1837, to the ruling families of various countries such as Russia, Spain, and Germany. Sovereign Victoria's gene for hemophilia was brought about by unconstrained mutation.
>Haemophilia is also called bleeder's disease. It is a type of disorder where an individual's blood can't clot normally. In typical blood, proteins considered coagulating components to cooperate to form a clot at whatever point bleeding happens. The individual with hemophilia lacks or needs more the specific clotting factor so the blood can't make a clot.
>Both Hemophilia A and hemophilia B are inherited in an X-linked recessive way. The genes related to these conditions are situated on the X chromosome, which is a part of the two human sex chromosomes.

So, the correct answer will be option D i.e, 'Y-linked disease'.

Note:There are multiple complications that can occur with hemophilia such as deep internal bleeding, destruction of the joint, various types of infections due to blood transfusions, weaker immune system, etc.
