Suddenly wiping out a large portion of the gene pool is known as the:
AGene flow effect
BMutation effect
CBottleneck effect
DFounder effect
Answer & Solution
Correct answer: C. Bottleneck effect
1. Chance events can remove alleles from a population wholesale.
2. An event may suddenly wipe out a large portion of the gene pool.
3. That is known as the bottleneck effect.
4. The founder effect instead starts a new population from an unrepresentative sample.
