A polygenic trait, is a trait that nonallelic genes control. These traits result from one or more genes contributing to the phenotype. An individual's physical appearance is determined by chromosomal inheritance and genotypic ratio.This phenomenon is known as Mendel's Laws of Inheritance.olygenic trait molding is done mostly with the environment and genes. More than one gene determines these traits, with each gene giving a small, yet additive effect. Multifactorial traits do not exhibit Mendelian ratios, and are determined between genes, or a gene, and the environment.
A trait that is controlled by multiple genes is called a. monogenetic trait. multigenetic trait. tri-genetic trait. polygenetic trait.
