Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Some diseases are linked to sex chromosomes.
These are called sex-linked diseases.
Step 2: Key Formula or Approach:
No specific formula.
Need to know sex-linked diseases.
Step 3: Detailed Explanation:
Colour blindness is a sex-linked (X-linked) disease.
It is caused by mutations in genes on the X chromosome.
Leukaemia, anaemia, and malignancy are not typically sex-linked.
They can be caused by various factors.
Thus, colour blindness is the sex-linked disease.
Step 4: Final Answer:
Colour blindness is a sex-linked disease.
Hence, the correct option is (D).
