Genetic Drift, Founder Effect, & Population Bottleneck

Genetic drift

a random and drastic change of allele frequencies in a population

Genetic drift is more likely to happen in (small/large) populations

small

Founder Effect

small group of individual establish a new population that has less genetic diversity than the original population

What is a real life example of the founder effect?

Amish people

Population Bottleneck

a population gets significantly smaller in size (due to an outside force), causing loss in genetic diversity

What is an outside force that can cause a population bottleneck?

humans hunt a population to near extinction

A small population generally has (more/less) genetic diversity than a large population

less
