[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. eastern mountain sports soldWitrynaSolution. 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? cui network one distributionSince 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).
