Question

Genetic disorder hemophilia is characterized by excessive loss of blood. Which of the following statement is not true in relation to this disease?

• A. It is an autosomal disease.
• B. It is a X-linked disease.
• C. Any of the factor VIII or IX may be absent.
• D. It is a lethal disease.

Answer 1

The correct option is A It is an autosomal disease.

Hemophilia is a mostly genetic inherited disorder that impairs the body ability to make blood clots, a process needed to stop bleeding. This is a sex-linked recessive disease, which shows its transmission from unaffected carrier female to some of the male progeny. There are two main types of hemophilia- Haemophilia A, which occurs due to not enough clotting factor VIII, and Haemophilia B, which occur due to not enough factor clotting IX.

So the correct option is "It is an autosomal disease".
