Which evolutionary process can lead to a reduction in genetic diversity in a small population?
Answer
Genetic drift
The correct answer is Genetic drift — Therefore, genetic drift is the correct answer.
Step-by-step solution
- Identify which evolutionary process reduces genetic diversity in small populations, which is genetic drift.
- From the options, mutation introduces new alleles but does not reduce diversity; natural selection may reduce diversity but not primarily; gene flow increases diversity; genetic drift reduces diversity randomly.
- Therefore, genetic drift is the correct answer.
Common mistake: Confusing drift with selection
Concept tested: Reduction of diversity by drift
