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.
Human skin, hair, and eye color are also polygenic traits because they are influenced by more than one allele at different loci. The result is the perception of continuous gradation in the expression of these traits.
