Polygenic traits are controlled by more than one genes. An example of this on humans is height. Not one gene controls the height of a human, many traits contribute to the height of a human.

Polygenic traits basically mean the traits that are a result of multiple intertwined traits like for example skin colour.

When two people mate their traits get intertwined and the resultant trait of the baby is a result of the polygenic traits.
