Solution

Bottleneck Effect:

  1. The bottleneck effect is an extreme example of genetic drift.
  2. It happens when the size of a population is severely reduced.
  3. Events like earthquakes, floods, and fires can decimate a population causing this effect.
  4. It kills most individuals and leaves behind a small, random assortment of survivors.
  5. As an example, Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction.
  6. This is reducing the size of their populations.
  7. Cheetahs' self-genes also pose a challenge to their continued survival.
