Genetic Explanation for Similarities in Personalities of Twins Raised Apart

Abstract

Twins living in different countries provide a unique chance to delve into the connections between the differences we observe and the experiences they go through. The life stories, cognitive abilities, personality traits, psychomotor abilities, health histories, job satisfaction, social support, and relationships of dizygotic (DZ) female twins the longest-separated twins in history are examined in greater detail in this report. The twins were reunited at the age of 78. Their advanced age also allowed researchers to examine how differences between the twins in aging might relate to their current behaviours and social interactions. In line with earlier studies, these dizygotic twins raised apart (DZA) displayed inconsistencies in some traits, but not in all. The disparities in their reactions to meeting each other are probably explained by the different upbringings and life experiences they had.  Although it doesn't offer conclusive answers about the extent to which genetic and parenting variables contribute to individual developmental differences, this case highlights the importance of both in influencing behaviour.  However, this data contributes to the expanding corpus of studies on twins reared in diverse cultural contexts, generating novel theories that can be investigated with bigger sample sizes.
