Polygenic Inheritance

Skin color is a really good example of polygenic inheritance. Polygenic inheritance deals with multiple genes for a single trait. The many genes explains why there is a wide variation between phenotypes and there are many different skin colors.( Armstrong, W.P. 2001) Another example of polygenic inheritance in humans is height and eye color.
