Why is it particularly useful to study identical twins who were raised in different environments?

  • A. Differences in brain function can be easily 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 are due to their being treated more similarly than nonidentical twins.
Correct Answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.
