Summary Introduction
To review:
The mechanism by which genetic drift and gene flow affect the population.
Introduction:
The population can be defined as a group of individuals of the same species residing in the same geographical area. The process of natural selection favors the fittest members of the population and transmits their genes to the next generation. The other factors besides natural selection to favor evolution in a population are genetic drift, gene flow, and selective hunting.

Explain why the genetic structure of populations changes across space and time?
Compare and contrast the effects of mutation, migration, genetic drift, and natural selection on genetic variation within populations and on genetic divergence between populations.
Explain how mutation, genetic drift, and gene flow can all contribute to changes in allele frequencies.
