Chapter 13, Problem 5LTB
Summary Introduction
Introduction:
Two major mechanisms which govern the evolution are genetic drift and natural selection. Natural selection can be defined as the process by which genetic characters increase the chances of survival and reproduction of an organism.

Which of the following statements explains genetic variation? Genetic variation arises ____.
When organisms need to change to survive in a new environment.
