Question

Match items in List I with List II:

• A. A-II, B-IV, C-III, D-I
• B. A-I, B-IV, C-III, D-II
• C. A-I, B-III, C-IV, D-II
• D. A-II, B-III, C-IV, D-I

Hint:

Remember: Pink flowers = Incomplete; Blood types = Codominant.

Answer 1

The Correct Option is D

Step 1: Concept
Match classic genetic phenomena with their textbook model organisms.

Step 2: Meaning
Incomplete dominance results in intermediate phenotypes (e.g., Pink flowers from Red and White parents in Mirabilis jalapa).

Step 3: Analysis
A-II (4 o'clock plant). Recessive epistasis explains mouse coat color (B-III). Dominant epistasis is seen in summer squash (C-IV). Codominance is best shown by ABO blood groups where both A and B are expressed (D-I).

Step 4: Conclusion
The correct matching sequence is A-II, B-III, C-IV, D-I. Final Answer: (D)
