Personality Correlations Between Mothers and their Biological Children
Adoption and twin studies such as Horn, Loehlin, and Willerman (1979) and Bergeman et al. (1993) suggest that genetics has the most influence on the formation of the personality, while the environment has little to no influence. Studies such as Loehlin et al. (1998) argue that the uniqueness of individual children and their environments create differences in their personalities. The purpose of this study was to determine whether genetics or the environment has the most effect on the personality relationship between mothers and their biological children.
