Use reasoning to answer the following question. What can be reduced when a population suddenly gets much smaller?
Options:
- (A) Pollution
- (B) The size of the Earth
- (C) Greenhouse gasses
- (D) The size of bottlenecks
- (E) The size of the environment
- (F) Genetic variation
- (G) Plant growth is reduced
- (H) Quality of life
Bottleneck effect occurs when a population suddenly gets much smaller. Genetic variation can be reduced by random genetic drift, population bottlenecks, founder effect. Genetic variation can be reduced when a population suddenly gets much smaller.
So, the answer is (F).
