Quizplus · Accepted Answer

Polygenic inheritance refers to the concept that most characteristics or traits are influenced by the interaction of multiple genes, rather than being determined by a single gene. This means that each individual gene contributes a small amount to the overall expression of the trait, resulting in a continuous, quantitative variation in the population. Examples of polygenic traits include height, skin color, and intelligence.
