Question

X-linked disorders are called as royal diseases since they were prevalent in the Royal Family of England.

• A. True
• B. False

Answer 1

The correct option is B

False

Haemophilia is named as the royal disease because the family pedigree of Queen Victoria shows a number of haemophilic descendents as she was a carrier of the disease. While it is indeed the result of a defective gene on the X chromosome, not all X linked diseases are Royal diseases.
