Are fraternal twins similar in neuroticism?

Fraternal twins, or dizygotic twins, share about 50% of their genetic material, which can influence traits such as neuroticism. Research suggests that while they may exhibit some similarities in neuroticism due to shared genetics and environmental factors, they are generally less similar in this trait compared to identical twins. Environmental influences, individual experiences, and personal temperament also play significant roles in shaping neuroticism, leading to greater variability between fraternal twins. Overall, while there may be some correlation, it is not as strong as that observed in identical twins.
