A quality is supposed to be polymorphic if more than one allele possesses that quality's locus inside a populace. Notwithstanding having more than one allele at a particular locus, every allele should likewise happen in the populace at a pace of in any event 1% to for the most part be viewed as polymorphic. 

Quality polymorphisms can happen in any area of the genome. Most of polymorphisms are quiet, which means they don't change the capacity or articulation of a quality. Some polymorphism is noticeable. For instance, in hounds the E locus, can have any of five distinct alleles, known as E, Em, Eg, Eh, and e. Shifting blends of these alleles add to the pigmentation and examples found in hound coats. 

A polymorphic variation of a quality can prompt the unusual articulation or to the creation of a strange type of the protein; this anomaly may cause or be related with illness. For instance, a polymorphic variation of the quality encoding the catalyst CYP4A11, in which thymidine replaces cytosine at the quality's nucleotide 8590 position encodes a CYP4A11 protein that substitutes phenylalanine with serine at the protein's amino corrosive position 434. This variation protein has decreased compound movement in using arachidonic corrosive to the circulatory strain controlling eicosanoid, 20-Hydroxyeicosatetraenoic corrosive. An examination has indicated that people bearing this variation in either of their CYP4A11 qualities have an expanded rate of hypertension, ischemic stroke, and coronary corridor disease.
