Polygenic inheritance is not a special type of gene action but is the production of a phenotype by several pairs of genes, each with a small additive effect. Nearly ...


A gene is a specific DNA sequence that leads to the expression of an ... Some traits are considered to be polygenic traits, associated with a number of genes.


The collaboration of numerous genes to influence a phenotype constitutes a polygenic (i.e., “many gene”) trait. One example of a polygenic trait is human height.
