One of the original Amish settlers who founded a new area for them had a rare, genetic disorder which causes short limbs and extra digits. Now, many within the population show this trait.

Which type of Genetic Drift does this demonstrate?

• Gene Flow

• Founder Effect

• Bottleneck Effect

• Coevolution

During a hurricane, a population of beetles almost gets completely wiped out. The only beetles that survived were lucky that they were in their nest at the time of the hurricane and had enough food to survive.
