In the study by Neiss et al. (2006), the researchers found greater concordance for self-esteem in monozygotic (identical) twins compared to dizygotic (fraternal) twins. This suggests that genetic factors may play a significant role in influencing self-esteem, as identical twins share 100% of their genes, while fraternal twins share about 50%. The higher concordance in identical twins indicates a potential genetic component to self-esteem.
