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.
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.
