 3.4 How do researchers study the relationship between genetic inheritance and individual traits and behavior?

 3.5 How do genes and the environment interact?

Genes are the basic unit of our biological inheritance from our mother and father. In this chapter, we examine what we know about the effects of genes on children’s development. We begin with a brief historical view of the study of genetics and then describe genes and the basic ways in which they work. We then look at some types of disorders that are caused by genes and some promising ways of treating these disorders. Finally, we discuss the interaction of genes and environment to show that nature (genes) and nurture (environment) are so inextricably tied together that we cannot attribute most aspects of development separately to one or the other. As we said in Chapter 1, we have left behind the idea of nature versus nurture and have entered the era of nature through nurture.
