when more than one gene controls a trait and the result is often a continuum (gradient) of phenotypes rather only two distinctive options this is called Polygenic Trait.
A Polygenic Trait that is influenced by two or more genes, such as height or skin tone, is referred to as a polygenic trait and Polygenic Trait characteristics of phenotypes do not follow the laws of Mendelian inheritance since several genes are involved. Polygenic Trait inheritance refers to the regulation of a characteristic by more than one gene in which the dominant allele of each gene expresses just a portion of the Polygenic Trait and the whole phenotype is only produced in the presence of the dominant alleles of all multiple genes.
