Answer

C
The Minnesota Twin Study found that identical twins were less similar in personality than fraternal twins.
D
The Minnesota Twin Study has helped established support for the claim that heredity influences personality.

Explanation

Identical twins share nearly all their genes, while fraternal twins share about half on average. The Minnesota Twin Study found that identical twins were generally more similar in personality than fraternal twins, which supports a role for heredity. Therefore, the statement that identical twins were less similar is not true; the Jim twins’ striking similarities are consistent with the study’s findings.
