Question
Chapter 20.3, Problem 2LO
Summary Introduction
To determine: Theeffect of processes that can cause evolutionary change on Hardy-Weinberg equilibrium.
Introduction: The phenotypically plastic organism has high fitness because such organisms are highly suited for persistent environment and can adapt themselves in accordance with the gradually changing environmental conditions.
