Quizplus · Accepted Answer

Polygenic means that a trait is controlled by multiple genes, each contributing a small effect to the trait. This is true for almost every trait, including height, weight, intelligence, and personality traits. Nonadditive and X-linked traits are more specific categories that do not apply to all traits. Monozygotic refers to identical twins and is not a trait classification.
