Mar 1, 2023 · Both genetics and environment play a part in the development of personality, although the specific degree to which each one plays a part often depends on the specific personality trait in question. This article discusses how personality traits are defined, whether personality is genetic, and how traits can sometimes change over time.
As we described earlier, Turkheimer's (2000) three laws are actually statements about the typical values of a 2, c 2 and e 2 found in behavior genetic research. For personality traits, a 2 tends to be around 50% of p 2, c 2 tends to be around 0% of p 2, and e 2 tends to be around 50% of p 2 (Bouchard & Loehlin, 2001).

Abstract. In recent years, substantial effort has gone into disentangling the genetic contribution to individual differences in behaviour (such as personality and temperament traits). Heritability estimates from twin and family studies, and more recently using whole genome approaches, suggest a substantial genetic component to these traits.
