Isomorphism vs. Polymorphism: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on January 20, 2024
Isomorphism is a similarity in form or structure in different objects; Polymorphism is the ability to take on multiple forms.
Key Differences
Isomorphism refers to the correspondence between elements of two systems that preserves the structure, while polymorphism in programming is an object-oriented concept where a function or object operates in several different ways. Both concepts, though used in different contexts, deal with the idea of transformation and adaptability, but in isomorphism, the focus is on maintaining structure, and in polymorphism, it's about versatility in function.
In mathematics, isomorphism implies a mapping between two structures that is both a homomorphism and invertible, showing a form of symmetry between them. On the other hand, polymorphism in biology refers to the occurrence of different forms or types in individuals among the members of a single species, showing diversity in characteristics. While isomorphism emphasizes structural similarity, polymorphism highlights the existence of multiple distinct forms.
Isomorphism in social sciences may refer to organizations adopting similar structures or processes, while polymorphism in computer science allows for objects of different classes to be treated as objects of a common superclass. Isomorphism here implies conformity to a model or standard, whereas polymorphism represents flexibility and dynamic behavior in system design.
In crystallography, isomorphism denotes the similarity in crystalline structure between different compounds, while in genetics, polymorphism is about the occurrence of different alleles of a gene in a population. Isomorphism in this context is about the similarity in the fundamental arrangement, whereas polymorphism is about variation and diversity at a genetic level.
Isomorphism can also be seen in linguistics, where it refers to similar grammatical structures across different languages. In contrast, polymorphism in cultural studies might refer to the existence of multiple cultural practices or beliefs within a single community. Here, isomorphism highlights structural parallels, whereas polymorphism indicates diversity within a single system.

Isomorphism and Polymorphism Definitions
Isomorphism
In crystallography, similarity in crystal forms of different substances.
Despite their chemical differences, the isomorphism of these minerals is striking.
Polymorphism
In biology, the occurrence of different forms or types within the same species.
The polymorphism seen in the butterfly population results in a variety of wing patterns.
Isomorphism
A similarity in mathematical structures.
The isomorphism between algebraic structures made the two systems virtually interchangeable.
Polymorphism
In cultural studies, the coexistence of multiple traditions or practices within a single community.
The city's cultural polymorphism is evident in its diverse culinary landscape.
Isomorphism
In biology, similarity in body structures across different species.
The isomorphism observed in the skeletal structures of mammals reveals their evolutionary relationships.
Polymorphism
In genetics, the existence of two or more distinct alleles at a locus.
Genetic polymorphism is a key factor in the study of evolutionary biology.
Isomorphism
In linguistics, similarity in grammatical structures across languages.
The isomorphism between these languages' syntax simplifies learning for speakers.
Polymorphism
In materials science, the ability of a solid material to exist in more than one form or crystal structure.
The polymorphism of this mineral results in different physical properties under varying conditions.
Isomorphism
In sociology, similar structures or processes in different organizations.
The isomorphism in educational institutions globally reflects standardized practices.
Polymorphism
In computer science, the ability of a function to process objects differently based on their class or data type.
Polymorphism in this programming language allows for flexible and dynamic code design.
Isomorphism
(Biology) Similarity in form, as in organisms of different ancestry.
Polymorphism
(Biology) The occurrence of more than one form, as several alleles of a particular gene or winged and wingless forms of the same species.
Isomorphism
(Mathematics) A one-to-one correspondence between the elements of two sets such that the result of an operation on elements of one set corresponds to the result of the analogous operation on their images in the other set.
Polymorphism
(Chemistry) Crystallization of a compound in at least two distinct forms. Also called pleomorphism.
Polymorphism
The ability to assume different forms or shapes.
Polymorphism
(biology) The coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents.
Polymorphism
(object-oriented programming) The feature pertaining to the dynamic treatment of data elements based on their type, allowing for an instance of a method to have several definitions. en
Polymorphism
The property of certain typed formal systems of allowing for the use of type variables and binders/quantifiers over those type variables; likewise, the property of certain expressions (within such typed formal systems) of making use of at least one such typed variable.
Polymorphism
(crystallography) The ability of a solid material to exist in more than one form or crystal structure; pleomorphism.
Polymorphism
(genetics) The regular existence of two or more different genotypes within a given species or population; also, variability of amino acid sequences within a gene's protein.
Polymorphism
Same as Pleomorphism.
Polymorphism
The capability of assuming different forms; the capability of widely varying in form.
Polymorphism
(chemistry) the existence of different kinds of crystal of the same chemical compound
Polymorphism
(biology) the existence of two or more forms of individuals within the same animal species (independent of sex differences)
