Question:
Large number of variations arise in natural populations of organisms due to ___________.
Large number of variations arise in natural populations of organisms due to ___________.
Show Hint
Mutations are rare, while sexual reproduction reshuffles existing alleles in each generation.
Updated On: Nov 12, 2026
- mutations
- gene flow
- genetic drift
- gene recombination
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Variation comes from mutation, gene flow, genetic drift and gene recombination.
Step 2: Compare
Mutations create new alleles but are rare.
Gene flow and genetic drift mainly change allele frequencies.
Step 3: Recombination
Crossing over, independent assortment and random fertilisation produce new gene combinations every generation, giving a large amount of variation.
Final Answer:
Most variation arises from gene recombination. \[ \boxed{\text{(D) }\text{gene recombination}} \]
