Question

What is the similarity between the two genes responsible for colour blindness and haemophilia?

WBBSE Class X Life Science 03 (b) Some Common Genetic Diseases 01 Mark 2024

Answer

Both genes are sex-linked recessive genes located on the X chromosome.

Explanation:

The genes for colour blindness and haemophilia are inherited as sex-linked traits, meaning they are carried on the X chromosome and are recessive. These conditions usually manifest in males, who have only one X chromosome.
