Question

Quizplus · Accepted Answer

Behavior geneticists use twin and adoption studies to assess trait heritability, which is the proportion of variation among individuals in a trait that can be attributed to genetics. These studies allow researchers to estimate the relative contributions of genetics and environment to a variety of traits and behaviors. Epigenetic marks, reproductive capacity, and brain injuries are not directly measured using twin and adoption studies.
