a gene, phenotype, or genotype that is so overwhelmingly common among those possible at a locus of interest that it is, in effect, the standard characteristic, and therefore presumably not harmful.

adjective Referring to an organism or gene locus that predominates in natural or normal populations.
noun The normal condition of a whole organism (wild-type strain) or a particular mutation at a locus or site, which is indicated by a plus sign. The allele of a particular gene that confers the phenotype considered to be the "normal" type commonly found in natural populations. Because some DNA sequence polymorphisms do not produce different phenotypes, there can be multiple "wild-type" alleles of a gene.
noun The naturally occurring phenotype of an organism; a strain of organism used as a standard reference with which to compare mutant derivatives.

wild type(wīld tīp)
A gene, phenotype, or genotype that is overwhelmingly common among those possible at a locus of interest, and therefore presumably not harmful.
Medical Dictionary for the Health Professions and Nursing © Farlex 2012
wild typethe ‘normal’ PHENOTYPE present in a natural or laboratory population, as distinct from a MUTANT (2) type which often can survive only under artificial conditions. Wild type alleles are usually given a ‘plus’ symbol. Thus the wild type allele of the vestigial wing mutation (vg) in Drosophila is vg+.
