{Colour blindness = defect in cone cells}.
Updated On: Feb 4, 2026
- Presence of non functional retinal cone cells lead to colour blindness
- Y-linked inheritance is criss-cross in human beings
- X-linked disorders very frequently appear in human females
- In human being carrier females are colour blind
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding colour vision.
Cone cells in the retina are responsible for colour vision.
Step 2: Cause of colour blindness.
Non-functional or defective cone cells result in colour blindness.
Step 3: Eliminating incorrect statements.
Y-linked inheritance is not criss-cross, X-linked disorders are more common in males, and carrier females are not colour blind.
