The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
• The question asks for the name of the concept of genetic variability in the gene pool arising from mutation, variation and heredity.
Step 2: Detailed Explanation:
• Darwinism alone does not account for the source of heritable variation.
• Neo-Darwinism combines Darwin's natural selection with genetic variation introduced by mutation and recombination.
• As per the NTA final answer key the correct term is Neo-Darwinism.
Step 3: Final Answer:
The correct option is (B) Neo-Darwinism.
• The question asks for the name of the concept of genetic variability in the gene pool arising from mutation, variation and heredity.
