(a)

Summary Introduction

To draw: A graph depicting the phenomenon of no selection with a range of phenotype (e.g. height) on the x-axis and number of the individual on the y-axis.

Introduction: The phenomenon of natural selection is based on the evolutionary changes that occur within the population.

(b)

Summary Introduction

To draw: A graph depicting the phenomenon of “stabilizing selection” with a range of phenotype (e.g. height) on the x-axis and number of the individual on the y-axis.

Introduction: The phenomenon of natural selection is based on the evolutionary changes that occur within the population. The mechanism of natural selection can be classified into three kinds: stabilizing selection, directional selection, and disruptive selection.
