Genes in Context: Gene–Environment Interplay and the Origins of Individual Differences in Behavior

ABSTRACT— Interactions between genes and the environment are a critical feature of development. Insights into the dynamic interplay between these factors have come from laboratory studies exploring experience-dependent changes in gene function, which illustrate the importance of environmental factors in determining activity of the genome. These studies have implications for our understanding of the origins of individual differences in behavior and may provide new ways of thinking about the transmission of traits across generations. Here we will highlight how these new findings illustrate the importance of putting genes in context.
