Polymorphism
in biology, occurrence of two or more clearly different morphs or forms in the population of a species / From Wikipedia, the free encyclopedia
Polymorphism [1] in biology is when two or more clearly different phenotypes exist in the same population of a species.[2] The words forms or morphs are sometimes used.[3]

Polymorphism is common in nature. The most common example is sexual dimorphism, which occurs in many organisms. Another example is sickle-cell anaemia.
In order to be classified as such, morphs must occupy the same habitat at the same time and belong to a population with random mating.[4]
