Detailed explanation-1: -The wild type (WT) is the phenotype of the typical form of a species as it occurs in nature. Originally, the wild type was conceptualized as a product of the standard “normal” allele at a locus, in contrast to that produced by a non-standard, “mutant” allele.
Detailed explanation-2: -The wild type is the most common form or phenotype in nature or in a natural breeding population.
Detailed explanation-3: -Wild type refers to the most common phenotype in the natural population. Wild type also refers to the allele at each locus required to produce the wild-type phenotype. Wild type is the standard of reference for the genotype and phenotype. As the standard, wild type is not considered dominant or recessive.
Detailed explanation-4: -In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color.
Detailed explanation-5: -Drosophila of typical appearance are said to show the “wild-type” forms (phenotypes) of genetically-controlled traits for body colour, eye colour, wing shape, etc.
