Abstract

Behavioral genetics is a field of scientific research that aims to understand how much genetic and environmental factors contribute to variability in behavior. From a genetics standpoint, numerous genes are influenced by the environment, which results in complex behaviors. Additionally, the physiology and developmental history of an individual, along with its environment, can modify genes and neuronal circuits of the brain. Furthermore, evolution and natural selection shape behaviors to optimize survival of the individual. Behavioral genetics is an evolving field that involves a combination of experimental psychology, genetics, neuroscience, and ethology.
