This diagram shows __________ __________

This diagram shows Genetic Drift

What is Genetic Drift?

Change in frequency of a gene variant (allele) due to random

What is geographic isolation?

Species isolated due to the geography of the environment. Eventually new species development

What is behavioral isolation?

Reproductive isolation in which two populations have differences in courtship rituals or other types of behavior that prevents them from interbreeding

Draw/Give an example of temporal isolation
