Quizplus · Accepted Answer

Polygenic inheritance occurs when multiple sets of alleles affect the same trait in an additive fashion. This means that each allele contributes a small amount to the phenotype, and the overall phenotype is determined by the sum of these contributions. This process can result in a wide range of phenotypic variation, as seen in traits such as height, skin color, and intelligence.
