A monogenic inheritance depends on only one single allele while a polygenic inheritance depends on multiple alleles. Monogenic refers to qualitative traits and polygenic refers to quantitative traits.
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.
