Question

Quizplus · Accepted Answer

Adoption studies compare children's traits with their adoptive and biological parents' traits. This helps researchers to understand the contributions of both genetics and environment on different traits and behaviors. The other options (A, C, and D) are incorrect. Option A refers to twin studies, not adoption studies. Option C is incorrect as adoption studies can be conducted on non-twin siblings as long as they have been adopted into different families. Finally, option D is incorrect as adoption studies actually help to show the relative influence of both genetics and environment, rather than suggesting that one is more important than the other.
