Detailed explanation-1: -A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance . Many polygenic traits are also influenced by the environment and are called multifactorial.

Detailed explanation-2: -The term pleiotropy is derived from the Greek words pleio, which means “many, ‘’ and tropic, which means “affecting.” Genes that affect multiple, apparently unrelated, phenotypes are thus called pleiotropic genes (Figure 1).

Detailed explanation-3: -Polygenic traits are determined by multiple genes received from each parent. Explanation; Polygenic traits are traits or characteristics that are controlled by many genes. They are controlled by two or more than two genes at different loci on different chromosomes.
