Eye color is a polygenic trait. Height and skin color are also polygenic traits. If there is a vast variation in a trait, it's likely that it is polygenic.
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of oth
Examples of polygenic inheritance in humans include height, eye color and skin color. Physical traits that have polygenic inheritance are influenced by more than one gene and typically display a continuous distribution, such as a range of heights. Polygenic traits do not have the classic phenotypic

polygenic: [ pol″e-jēn´ik ] pertaining to or determined by several different genes.
A polygenic trait is a characteristic, sometimes we call them phenotypes, that are affected by many, many different genes. A classic example of this would be height. Height in humans is very strongly genetically controlled, but there are many, many different genes that control height.
Polygenic traits also have dominant and recessive alleles, but so many genes play a role in an organism’s phenotype for these traits that the final result is the sum of many complex interactions. It can be hard or impossible to figure out one gene’s effect on a polygenic trait.
The term polygenic comes from poly, meaning “many” and genic, meaning “of genes”.. Polygenic vs. Mendelian inheritance. A polygenic trait is a trait that arises from polygenic inheritance.A polygenic inheritance is a non-Mendelian, which means that it does not follow Mendelian laws.
Polygenic Inheritance Definition. Polygenic inheritance is defined as quantitative inheritance, where multiple independent genes have an additive or similar effect on a single quantitative trait.Polygenic inheritance is also known as multiple gene inheritance or multiple factor inheritance.
Polygenic Inheritance Definition. Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.. In a system which differs from Mendelian Genetics, where monogenic traits are determined by the different alleles of a single gene, polygenetic traits may display a range of possible phenotypes ...
