Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of genetic diversity and its conservation.
Step 2: Detailed Explanation:
Genetic erosion is the gradual loss of genetic variability from the germplasm of a crop.
It occurs due to the replacement of traditional varieties with modern high-yielding varieties.
Pleiotropy (A): A single gene affecting multiple traits.
Mutation (B): A change in the DNA sequence.
Inbreeding depression (C): Loss of vigour due to inbreeding.
Thus, genetic erosion is the correct answer.
Step 3: Final Answer:
Thus, gradual loss of variability from germplasm is genetic erosion, which corresponds to option (D).
