Why is it particularly useful to study identical twins who were raised in different environments?
A) Differences in brain function can easily be identified.
B) Concordance rates tend to be higher.
C) It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D) It is possible that high concordance rates between identical twins reared together is due to their being treated more similarly than nonidentical twins.

Question

Quizplus · Accepted Answer

Studying identical twins raised in different environments allows researchers to disentangle the effects of genetics and environment on various traits and behaviors. If identical twins, who share the same genetics, show high concordance rates despite being raised in different environments, it suggests that genetics play a significant role in those traits. This approach helps to address the concern that high concordance rates among twins raised together might be due to similar treatment rather than genetics alone.
