- Crystallization of a compound in at least two distinct forms.pleomorphism
- The occurrence of more than one form, as several alleles of a particular gene or winged and wingless forms of the same species. 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.
- 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.
