in human beings multiple genes are involved in the inheritance of
Polygene Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect.[8] Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well. Drosophila, for instance, display polygeny with traits such as wing morphology,[9] bristle count (20170808 dead link)[10] and many others.
