WebNov 22, 2024 · Polygenic inheritance results in an additive effect of the genes on a single phenotype. Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics. WebMay 8, 2024 · Descendants may inherit dominant or recessive variations of some of the genes, and the inherited genes influence each other in different ways. Some of the genes are expressed more or less strongly, and environmental factors may influence the trait as well. Typical examples of polygenic traits in humans are height, eye color and skin color.
