Many genes may interact to produce one trait.
... Traits that are produced by two or more genes are called polygenic traits. skin color, for example, is the result of four genes that interact to produce a many genes continuous range of colors. Similarly, poly genic human eye color, which is often thought of as a single gene trait, is polygenic. As ...
