Polymorphism, polymorphic or polymorph, from the Greek roots "poly" (many) and "morphe" (form, shape, structure), may refer to:

Polymorphism (computer science), the ability in computer programming to present the same programming interface for differing underlying forms (data types, classes)
Polymorphic code, self-modifying program code designed to defeat anti-virus programs or to defeat reverse engineers

Polymorphism (materials science), the ability of a solid material to exist in multiple forms or crystal structures known as polymorphs
Polymorphism (biology), the occurrence of more than one form in the same population of a species.
Genetic polymorphism, is the branching of the genetic tree, caused by two or more alleles (gene forms) occurring at one DNA position or in one DNA region, each with appreciable frequency in the population. Examples are:
- Single-nucleotide polymorphisms (SNP), the existence of alternative point-mutations in one single base pair
- Restriction fragment length polymorphism (RFLP)
- Amplified fragment length polymorphism (AFLP)
Polymorph, short for polymorphonuclear leukocyte or granulocyte, a type of white blood cell
Polymorph, a trade name for the low melting-temperature polymer, Polycaprolactone
Lipid polymorphism, the property of amphiphiles that gives rise to various aggregations of lipids
Polymorphic QRS complex, a wave pattern seen on an electrocardiogram
Polymorphous perversity, a concept in psychoanalytic theory

Ionogels of pseudogemini supra-amphiphiles in ethylammonium nitrate: Structures and properties.

Wang X1, Zhang Z1, Cao Y1, Hao J2.
Journal of colloid and interface science.J Colloid Interface Sci.2017 Apr 1;491:64-71. doi: 10.1016/j.jcis.2016.12.031. Epub 2016 Dec 18.
Thermoreversible ionogels formed by pseudogemini surfactants were prepared in protic ionic liquid, ethylammonium nitrate (EAN). Gemini-type supra-amphiphiles were formed by single-chain surfactants and bola-type molecules in a 2:1M ratio. The structures of aggregates including polymorphous lamellar

This current review focuses on current concepts and controversies for select key salivary gland epithelial neoplasms. Rather than the traditional organization of benign and malignant tumors, this review is structured around select key topics: biphasic tumors, mammary analogue secretory carcinoma, an

Angewandte Chemie (International ed. in English).Angew Chem Int Ed Engl.2017 Feb 13;56(8):2030-2034. doi: 10.1002/anie.201610977. Epub 2017 Jan 18.
Glycine, the simplest amino acid, is also the most polymorphous. Herein, we report the structure determination of a long unknown phase of glycine, which was first reported by Pyne and Suryanarayanan in 2001. To date, this phase has only been prepared at 208 K as nanocrystals within ice. Through co
