Genetic Drift

Changes in populations due to natural selection are due to fitness of an organism, which means

• random chance, like a natural disaster or migration to an island.

• genetic diversity is increased through immigration from another community.

• an organism's ability to survive and reproduce.

• the bottleneck effect.

Genetic Drift, unlike natural selection, is all up to

• camouflage.

• chance.

• fitness.

• evolution

The Founder Effect happens when

• a chance disaster occurs that kills randomly kills some of the population.

• a small group leaves their main population and starts a new population in a new area, like an island.

• changes in allele frequency occur due to natural selection

Bottleneck Effect can happen due to

• a natural disaster, like a forest fire or a flood.

• a small group leaves the main population and starts a colony somewhere new, like an island.

• allele frequency happens due to natural selection
