Question:
Given below are two statements:
Statement (I): Heat tolerant tropical cauliflowers show significantly high level of self-incompatibility.
Statement (II): The European annual or snowball types are basically self-compatible in nature.
In light of the above statements, choose the most appropriate answer from the options given below.

Statement (II): The European annual or snowball types are basically self-compatible in nature.
In light of the above statements, choose the most appropriate answer from the options given below.
Show Hint
Because snowball types are self-compatible, hybrid seed production in them relies on male sterility rather than self-incompatibility.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Self-incompatibility (SI) systems in Brassica oleracea vary depending on the ecological adaptation and evolutionary background of different groups.
Step 2: Detailed Explanation:
Statement (I) is true because heat-tolerant, tropical Indian cauliflowers (Group I and II) are highly cross-pollinated and exhibit a strong and reliable sporophytic self-incompatibility system. This system is actively utilized in F1 hybrid production.
Statement (II) is true because European temperate or Snowball cauliflower types evolved in cooler climates where insect activity was lower, leading to natural selection favoring self-compatibility.
Thus, both statements are correct.
Step 3: Final Answer:
The correct option is (A) as both statements are true.
