Final answer:
The heritability of personality traits such as leadership, obedience to authority, well-being, and others have a very high degree of heritability, meaning they are largely controlled by genetics.
Step-by-step explanation:
In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart conducted research with twins and found that personality traits such as leadership, obedience to authority, a sense of well-being, alienation, resistance to stress, and fearfulness have a very high degree of heritability. Heritability refers to the proportion of difference in personality traits among people that is attributed to genetics. These findings suggest that some aspects of our personalities are largely controlled by genetics, but traits are not determined by a single gene, but by a combination of many genes.
