behavioral genetics
Genes-influencing-actions research
Behavioral genetics is the scientific study of how genes influence behavior, personality, and mental traits.
The field examines heritability—what portion of variation in traits like intelligence, temperament, or susceptibility to mental illness can be attributed to genetic versus environmental factors.
Twin studies and adoption studies are its classic methods: Behavioral genetics research suggests that about half the variation in personality is heritable.
