Question

Quizplus · Accepted Answer

Research suggests that personality traits are strongly influenced by genetics, with estimates ranging from 40% to 60%. This means that siblings who share genes are likely to have similar personality traits, even if they have different environments. The shared environment, such as growing up in the same household, has a weaker influence on personality similarities compared to genetics. Nonshared environmental factors, such as different experiences and relationships outside of the family, also contribute but to a lesser extent. Therefore, the best choice is C: genetics.
