Answer:
genetic influences on personality
Step-by-step explanation:
Personality traits are influenced by both inheritance (genes) and environmental (e.g., educational, cultural background) factors, as well as by the interaction between genetic and environment. In genetics, it has been believed that personality traits have a strong genetic component, which has been observed in large-scale twin studies. Some personality traits that have been shown to have a strong genetic component include neuroticism, agreeableness, extraversion and openness. These traits are influenced by the combined effects of numerous genes (i.e., they are complex quantitative traits), thereby a significant number of researchers in other fields argue that the genetic components of personality traits are often overestimated.
