Question

Given below are two statements:
Statement I: Cleistogamy and chasmogamy favour self-fertilization.
Statement II: Male sterility and self-incompatibility do not favour cross-fertilization.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Pollination mechanisms:
- Selfing: Cleistogamy, Chasmogamy.
- Cross-fertilization: Male sterility, Self-incompatibility, Dichogamy.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests knowledge of pollination mechanisms.

Step 2: Detailed Explanation:
Statement I:
Cleistogamy (closed flowers) and chasmogamy (open flowers with selfing) favour self-fertilization.
This is correct.
Statement II:
Male sterility and self-incompatibility favour cross-fertilization.
They prevent self-fertilization and promote outcrossing.
Thus, this statement is false.

Step 3: Final Answer:
Thus, Statement I is correct but Statement II is false, which corresponds to option (C).
