If you look up the definition of Polygene, it says "A polygene or multiple gene inheritance is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait." Examples of Polygenic Inheritance are described as skin color, eye color, hair color, body shape, height, and weight. Also, since poly means multiple, it wasn't too hard to assume that "polygene" means multiple genes working together. Hope this helps!
