Abstract: | Monozygotic twins reared in different countries are rare. Data from several available cases have been combined in group findings, masking cultural effects on behavior. The present study compared behavioral and health-related findings for unusual monozygotic female twins raised apart in South Korea and the United States. The 37-year-old twins were exceptional in being reared under dramatically different circumstances with limited telephone and Internet contact. Primary outcome measures included life history events, physical and health-related characteristics, and diverse behavioral traits. Striking similarities and differences were noted. Findings are discussed with reference to genetic and cultural influences on health and behavior. |
