Final answer:
The Minnesota Study of Twins Reared Apart found that temperaments are strongly correlated for monozygotic twins, but virtually uncorrelated for dizygotic twins, demonstrating the heritability of certain personality traits.
Step-by-step explanation:
The Minnesota Study of Twins Reared Apart provides significant evidence regarding the influence of genetics on temperaments and personality. The study observed the personality traits of both monozygotic (identical) and dizygotic (fraternal) twins who were reared apart. The findings indicated a stronger correlation in the temperaments of monozygotic twins than dizygotic twins, reflecting a higher heritability for certain personality traits such as leadership and obedience to authority, among others. The correct response reflects the high heritability of these traits in identical twins irrespective of their upbringing.
From the given information, the answer to the schoolwork question would be:
c. strongly correlated for monozygotic twins, but virtually uncorrelated for dizygotic twins.
