Which research method allows researchers to MOST easily isolate the effect of both genetics and experience on specific traits?

C) adoption studies
D) survey studies

Question

Quizplus · Accepted Answer

Adoption studies allow researchers to observe individuals who are not biologically related to their adoptive parents, thus allowing for the isolation of the effects of genetics and experience on specific traits. Family studies and survey studies may not control for genetic factors, as family members share genetic similarities, and survey studies may not provide enough control over environmental factors. While twin studies can isolate genetic factors, they may not fully control for environmental factors.
