Chapter 8, Problem 4PDT

a.

Summary Introduction

To determine: Whether a cline in body size is a result of variation in allele frequencies at loci that affect body size.

Introduction: The movement of genetic variation from one population to another population is known as gene flow. Dispersal is the movement of individuals or gametes and it is responsible for gene flow from one place to another place. The environment plays an important role in phenotypic changes in an individual.

c.

Summary Introduction

To determine: The way selection varies in space with respect to the cline in body size of a squirrel when latitude changes.
