Alleles are the genetic variations in a population, and they are the driving force behind the evolution of that population. Mostinvestigations have focused on two of the most prominent patterns innature: (1) adaptation, or the ‘fit’ between organism andenvironment; or, (2) polymorphism, the maintenance of two or morephenotypic or genetic forms in a single population.
