Genetic polymorphisms meaning
WebIncomplete lineage sorting, also termed hemiplasy, deep coalescence, retention of ancestral polymorphism, or trans-species polymorphism, describes a phenomenon in population genetics when ancestral gene copies fail to coalesce (looking backwards in time) into a common ancestral copy until deeper than previous speciation events. It is caused … Webpolymorphism: [noun] the quality or state of existing in or assuming different forms: such as. existence of a species in several forms independent of the variations of sex. existence of a molecule (such as an enzyme) in several forms in a single species. the property of crystallizing in two or more forms with distinct structure.
