<p><b>New page</b></p><div>'''Polymorphism''' is a term used in various disciplines with different meanings. In the context of biology, it refers to the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. In order to be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating).<br />
<br />
== Biology ==<br />
<br />
In biology, '''[[polymorphism]]''' is a major aspect of [[biodiversity]]. It is defined as the occurrence of two or more different morphs or forms in the population of a species. The concept was first introduced by English biologist [[John Lubbock, 1st Baron Avebury|John Lubbock]] in 1889.<br />
<br />
=== Genetic Polymorphism ===<br />
<br />
'''[[Genetic polymorphism]]''' is a type of polymorphism where the phenotype is influenced by the genotype of an individual. It can be caused by multiple alleles of a gene within a population or by the interactions between two or more genes.<br />
<br />
=== Balanced Polymorphism ===<br />
<br />
'''[[Balanced polymorphism]]''' is a type of polymorphism where the frequencies of the morphs remain stable over many generations. This is due to the fact that no single morph has an overall advantage or disadvantage over the others in terms of survival and reproduction.<br />
<br />
== Computer Science ==<br />
<br />
In computer science, '''[[polymorphism]]''' is a programming language feature that allows values of different data types to be handled using a uniform interface. The concept was introduced by [[Christopher Strachey]] in the 1960s.<br />
<br />
=== Ad hoc Polymorphism ===<br />
<br />
'''[[Ad hoc polymorphism]]''' is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, but behave differently depending on the type of the argument.<br />
<br />
=== Parametric Polymorphism ===<br />
<br />
'''[[Parametric polymorphism]]''' is a way to make a language more expressive while still maintaining full static type-safety.<br />
