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.
Lesson Summary. In summary, traits that are polygenic are controlled by two or more genes. The Swedish geneticist Nilsson-Ehle used wheat and kernel color to first explore the concept of polygenic inheritance.olygenic Traits. If you were to graph out a trait or phenotype that is polygenic, you would notice a trend. These traits have what's called continuous variation, showing a bell curve of values for the phenotype.
