Some implementations of type polymorphism are superficially similar to parametric polymorphism while also introducing ad hoc aspects. One example is C template specialization . The most general form of polymorphism is higher rank impredicative polymorphism . Two popular restrictions of this form are restricted rank polymorphism for example, rank 1 or prenex polymorphism and predicative polymorphism.

In genetics , chromosomal polymorphism is a condition where one species contains members with varying chromosome counts or shapes. Polymorphism biology Polymorphism is a general concept in biology where more than one version of a trait is present in a population. In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form one. This condition has been detected in many species. Trichomycterus davisi , for example, is an extreme case where the polymorphism was present within a single Chimera genetics chimeric individual. ref cite journal journal Genet. Mol.

Polymorphism In programming language theory , subtyping or subtype polymorphism is a form of type polymorphism in which a subtype is a datatype that is related to another datatype the supertype by some notion of substitutability , meaning that program constructs, typically subroutines or functions, written to operate on elements of the supertype can also operate on elements of the subtype. If S is a subtype of T, the subtyping binary relation relation is often written S T, to mean that any term of type S can be safely used in a context where a term of type T is expected. The precise semantics of subtyping crucially depends on the particulars of what safely used in a context where means in a given ... a term to have belong to more than one type, subtyping is a form of type polymorphism , so it is properly called subtype polymorphism.

Single strand conformation polymorphism SSCP , or single strand chain polymorphism, is defined as conformational difference of single stranded DNA nucleotide sequences of identical length as induced by differences in the sequences under certain experimental conditions. This property allows to distinguish the sequences by means of gel electrophoresis , which separates the different conformations. Physical background A single nucleotide change in a particular sequence, as seen in a double stranded DNA, cannot be distinguished by electrophoresis, because the physical properties of the double strands are almost identical for both alleles. After denaturation, single stranded DNA undergoes a 3 dimensional folding and may assume a unique conformational state based on its DNA sequence. The difference in shape between two single stranded DNA strands with different sequences can cause them to migrate differently on an electrophoresis gel, even though the number of nucleotides is the same, which is, however, a shortfall of SSCP. Applications in molecular biology SSCP used to be a way to discover new DNA polymorphisms apart from DNA sequencing, but is now being supplanted by sequencing techniques on account of efficiency and accuracy. These days, SSCP is most applicable as a diagnostic tool in molecular biology. It can be used in genotyping to detect homozygous individuals of different allelic states, as well as heterozygous individuals that should each demonstrate distinct patterns in an electrophoresis experiment. SSCP is also widely used in virology to detect variations in different strains of a virus, the idea being that a particular virus particle present in both strains will have undergone changes due to mutation, and that these changes will cause the two particles to assume different ... polymorphism analysis and nucleotide sequencing of a fragment from the nucleocapsid gene ...
