Definition of Polygenic Traits
Polygenic traits are those traits which are being controlled by several genes. Traits are defined as any feature of an organism. Phenotype deals with physical appearance whereas genotype deals with genetic makeup. The genes that are responsible for controlling such traits are either located near to each other or on separate chromosomes.
These traits do not follow such a pattern of inheritance deduced by Mendel as multiple genes are playing their role. They are not measured discretely but are represented as a range having a continuous variation. The examples of polygenic traits include height, the colour of hair, eye and skin, etc.
