Behavior genetics, also known as psychogenetics, is the study of how much heredity and how much environment contribute to individual differences.
<h3>What area of research examines how the environment affects how genes are expressed?</h3>
A new field of study called "epigenetics" demonstrates how environmental factors—experiences as a child—actually affect the expression of their genes.
The majority of the research done by genetic psychologists focuses on how particular genes affect personality and behavior in people. Given that monozygotic twins have identical genetic make-up, twin and adoption studies—both of which are frequently used in the field of genetic psychology—can aid in research on the role of heritability in traits.
