Quizplus · Accepted Answer

Traits that are controlled by two or more genes are known as polygenic traits. These traits exhibit a wide range of variation and are not simply determined by dominant or recessive alleles, but rather by the combined effects of multiple genes. Multifactorial traits are also influenced by environmental factors, while polygenic traits are solely controlled by genes.
