Inheritance pattern requiring the influence of several (four or more) genes. The inheritance of characters such as height, weight and behavior depends on the simultaneous action of a number of genes in interaction with the environment. It is a form of inheritance that increases the probability that a character or trait will show continuous variation in a population.
