Answer: Traits that are controlled by multiple genes
Explanation: Polygenic traits are traits that are controlled by more than one gene. A trait that is influenced by only one gene is called a monogenic trait but when a trait is controlled by two or more genes, it is called a polygenic trait. The manifestation of these traits involves interaction of multiple genes. Polygenic traits do not obey Mendel's inheritance pattern. Examples of polygenic traits are skin colour, eye colour and hair colour.
