n.
1. Biology The occurrence of more than one form, as several alleles of a particular gene or winged and wingless forms of the same species.
2. Chemistry Crystallization of a compound in at least two distinct forms. Also called pleomorphism.

polymorphism

(ˌpɒlɪˈmɔːfɪzəm)
n
1. (Biology) biology
a. the occurrence of more than one form of individual in a single species within an interbreeding population
b. the occurrence of more than one form in the individual polyps of a coelenterate colony
2. (Chemistry) the existence or formation of different types of crystal of the same chemical compound

pol•y•mor•phism

(ˌpɒl iˈmɔr fɪz əm)

n.
1. the state or condition of being polymorphous.
2.
a. genetic variation that produces differing characteristics in individuals of the same population or species.
b. the occurrence of different castes or types within the same sex, as in social ants.
3. crystallization into two or more chemically identical but crystallographically distinct forms.

pol`y•mor′phic, adj.

pol·y·mor·phism

(pŏl′ē-môr′fĭz′əm)
1. The existence of two or more different forms in an adult organism of the same species, as of an insect. In bees, the presence of queen, worker, and drone is an example of polymorphism. Differences between the sexes and between breeds of domesticated animals are not considered examples of polymorphism.
2. The crystallization of a compound in at least two distinct forms. Diamond and graphite, for example, are polymorphs of the element carbon. They both consist entirely of carbon but have different crystal structures and different physical properties.

polymorphism

the occurrence of several forms or colors in one species of insect. — polymorphous, adj.

Noun1.polymorphism - (genetics) the genetic variation within a population that natural selection can operate on
genetic science, genetics - the branch of biology that studies heredity and variation in organisms

chemical phenomenon - any natural phenomenon involving chemistry (as changes to atoms or molecules)
dimorphism - (chemistry) the property of certain substances that enables them to exist in two distinct crystalline forms
