Question

After a natural disaster, a population of 100,000 birds is reduced to just 1,000. How might this bottleneck affect genetic drift?

Accepted Answer

Genetic drift is likely to accelerate, leading to decreased genetic variation.

Answer

Gene flow will increase, reducing the effects of genetic drift.

Answer

Genetic variation will increase due to the population bottleneck.

Answer

The bottleneck will have no effect on genetic drift.
