Question:
Self incompatibility is seen in
Self incompatibility is seen in
Show Hint

Updated On: Nov 12, 2026
- Calotropis
- Apple
- Sunflower
- Thea
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Self-incompatibility is a genetic block in which the plant's own pollen fails to fertilise it.
Step 2: Examples
The textbook gives tobacco and Thea (tea) as examples of self-incompatibility.
Step 3: Compare the options
Calotropis shows herkogamy, sunflower shows protandry, and apple is cited for prepotency.
Final Answer:
Self-incompatibility is seen in Thea. \[ \boxed{\text{(D) }\text{Thea}} \]
