Research in behavioural genetics has shown that identical twins reared apart often have similar personality traits. This result suggests that both genetic inheritance and environmental factors contribute to personality.

Personality traits are under a significant degree of genetic influence, usually influenced by a very large number of genes but environmental influences also play a strong role. The environmental factors tend to make family members more different from one another, not more similar.
