Question
Chapter 22.3, Problem 2LO
Summary Introduction
To determine: The way in which genetic drift and natural selection can lead to
Introduction: Natural selection is the process by which the organisms are adapted in the environment to produce their offspring. The genetic drift is the variation in the genetic pool due to random sampling that leads to change in frequency of population.
