Polygenic traits are: Group of answer choices Rare, comprising just a few traits. Most traits are monogenic rather than polygenic. Controlled by two or more genes, and include traits such as skin color and height. Controlled by just one gene, and include traits such as ABO blood type or freckles. Usually caused by harmful mutations that lead to disease development.
