Role of Molecular Markers and their Significance

WitrynaAbstract. 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. 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?

[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.
