Question

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

Answer 1

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.
