What is the difference between polygenic and pleiotropy?

Some nation abashed pleiotropy and polygenic inheritance. The superiority separation between the two is that pleiotropy is when one deteriorate affects multiple characteristics (e.g. Marfan syndrome) and polygenic bequest is when one close is controlled by multiple genes (e.g. skin pigmentation).

What is a polygenic disorder controlled by?
