A small population is reduced by a storm so that only a few individuals remain, and rare alleles are lost. This is an example of:
Answer and explanation
Correct answer: D. The bottleneck effect
- Step 1: A sudden reduction in population size causes a bottleneck and loss of genetic diversity.
Answer
The bottleneck effect.
Why not the others: Gene flow, Directional selection and Founder effect don't fit.
