Since all polymorphism has a genetic basis, genetic polymorphism has a particular meaning: • Genetic polymorphism is the simultaneous occurrence in the same locality of two or more discontinuous forms in such proportions that the rarest of them cannot be maintained just by recurrent mutation or immigration, originally defined by Ford (1940). The later definition by Cavalli-Sforza & Bodmer (1971) is currently used: "Genetic polymorphism is the occurrence in the sam… WitrynaVariable number tandem repeat (VNTR): Locations in a genome where a short sequence of nucleotides is repeated adjacent to each other. The length of such a repeat is inherited and is termed functional when it influences gene expression. For 5-HT, the 5-HTT linked polymorphic region (5-HTTLPR) is the most commonly investigated VNTR.

The current predominant method of analyzing base substitution polymorphisms, RFLP analysis, is likely to be gradually supplanted by methods based on PCR because of the improved sensitivity and genotyping rate. The most promising PCR methods for analysis appear to be allele-specific PCR and single-stranded conformational analysis.
