Question
Chapter 18, Problem 1QP
Summary Introduction
To determine: The major differences in the methods that are used to study behavior genetics of single traits and polygenic traits.
Introduction: The field of science that uses genetics to study the differences in origin and nature of an individual is called behavior genetics. Interactions among environmental stimuli, genes, and nervous system result in different traits related to behavior.
