Chapter 22, Problem 5CR
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.
