What term describes the study that analyzes the influence of both genetic and environmental factors on behavior?

The study that analyzes the influence of both genetic and environmental factors on behavior is referred to as behavior genetics. This field examines how genetic predispositions and environmental factors interact to shape individual behavior, personality traits, and responses to various stimuli. Behavior genetics utilizes twin studies, family studies, and adoption studies to quantify the heritability of traits and understand the extent to which genetics versus environment influences behavior.

This approach is fundamental in understanding complex behaviors, as it emphasizes that neither genetics nor environment alone fully determines outcomes. Instead, it is the interaction between these two factors that provides a complete picture of behavior development. Thus, it incorporates insights from both genetics and psychology, making it a crucial area of study in neuroscience and behavioral sciences.
