Explanation: A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes". The genes work together to make one trait. Examples are skin, eye and hair color.
Answer: Single gene-pair inheritance occurs when a trait is linked to one gene-pair that consists of two alleles. This is also referred to as Mendelian inheritance. An allele is one part of the gene-pair. One allele is inherited from the father, and one is inherited from the mother.
