Accordingly, the goal of this study was to evaluate genetic and environmental influences on personality stability and change during the transition to adulthood using three waves of personality trait data. The influence of heredity and environment heritability estimates don’t reveal anything about the extent to which genes influence a single person’s traits heritability depends on how similar the environment is for a group of people.
