Question

Which one is a sex-linked disorder?

• A. Sickle cell anaemia
• B. Albinism
• C. Haemophilia
• D. Phenylketonuria

Answer 1

The correct option is C Haemophilia

Haemophilia A is a recessive X-linked genetic disorder resulting in a deficiency of functional clotting Factor VIII. Haemophilia B is also a recessive X-linked genetic disorder involving a lack of functional clotting Factor IX. Hemophilia is a sex-linked recessive disorder. These kinds of defects occur more often in men than in women.

So, the correct answer is 'Haemophilia'.
