Question

Quizplus · Accepted Answer

Many human behavioral traits, such as intelligence and personality, have been shown to exhibit genetic heterogeneity, meaning that different genetic variations can result in the same phenotype. This suggests that these traits are polygenic, and not simply determined by a single dominant gene or caused by mutations in structural genes.
