Polymorphic genes
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Put simply, polymorphism is when there are two or more possibilities of a trait … Web(1) The glycoprotein B (gB) on the viral envelope, encoded by the most widely characterised polymorphic gene, gpUL55 , is responsible for cytomegalovirus (CMV) entry into the host and could serve as a potential marker of pathogenicity.

A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. 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. Gene polymorphisms can occur in any … See more A rule of thumb that is sometimes used is to classify genetic variants that occur below 1% allele frequency as mutations rather than polymorphisms. However, since polymorphisms may occur at low allele frequency, this … See more A polymorphism can be any sequence difference. Examples include: • Single nucleotide polymorphisms (SNPs) are a single … See more Polymorphisms can be identified in the laboratory using a variety of methods. Many methods employ PCR to amplify the sequence of a gene.
