WitrynaIn molecular biology, restriction fragment length polymorphism (RFLP) is a technique that exploits variations in homologous DNA sequences, known as polymorphisms, in order to distinguish individuals, populations, or species or to pinpoint the locations of genes within a sequence. The term may refer to a polymorphism itself, as detected … WitrynaSolution. If an inheritable mutation appears in a population at high frequency, this is known as DNA polymorphism. Since inheritable mutations finally lead to evolution, hence study of DNA polymorphism is important from the evolutionary perspective. Was this answer helpful?

"WitrynaA gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. [1] In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic. [2] Gene polymorphisms can occur in any region of the genome. " - Importance of dna polymorphism

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. 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…
