Detailed explanation-1: -Hair color is inherited, and many genes are involved in the process. Sometimes, unexpected hair color can occur in a child because of a genetic mutation. Some of the genes involved in hair color also influence eye color and skin color. Hair color is the result of genetics.
Detailed explanation-2: -The human hair color is controlled by more than one gene. In this case, hair color is a polygenic trait, which exhibits polygenic inheritance. There are individuals who inherit different combinations of alleles that are responsible for hair colors.
Detailed explanation-3: -A trait that is influenced by two or more genes, such as height or skin tone, is referred to as a polygenic trait. Hair colour is, in fact, a polygenic trait. Human skin colour and eye colour are also examples of polygenic traits.
