Question

1. how does heredity influence personality?

Explanation:

Heredity provides the biological foundation. Traits like temperament (e.g., being more or less reactive) have a genetic basis. Twin and adoption studies show that genetic factors contribute to aspects such as introversion - extroversion tendencies. However, environment also interacts with heredity. For example, a genetically predisposed shy child may become more outgoing in a very nurturing social environment.
