Question

Quizplus · Accepted Answer

Twin studies allow researchers to compare the similarities and differences between identical and fraternal twins, who have different genetic relatedness. By analyzing the extent to which a trait is shared between twins, researchers are able to estimate the degree to which genetics contribute to the expression of that trait, or the heritability of the trait. Thus, twin studies are generally used to evaluate the heritability of traits."Genetic determinism" implies that traits are solely determined by one's genes, which is not entirely accurate. "Reciprocal determinism" refers to the dynamic interplay between individuals and their environment, and is not directly related to twin studies. "The success of adoption policies" is not a primary focus of twin studies.
