I have received a couple of emails about this post and thought I should clarify something.

Polymorphism as I mentioned is generally considered a type of polygenic inheritance. I did not mean to imply that the two terms are synonymous. It's more like polymorphism is one type of polygenism.

So both polygenic and polymorphic traits are thought to be controlled by multiple gene loci. The difference is that variation in a polygenic traits tend to occur along a continuum where polymorphic traits tend to have two or more discreet phenotypes that do not blend.

And both can show Mendelian patterns of inheritance if there is some sort of epistatic gene at work.
