Wild type refers to the gene, strain, or character which is most commonly found in the population in natural conditions.

The allele or the gene which is found rarely in the population is termed as mutant allele or character.

For example, the wild-type phenotype of fur color of tigers is orange with black strips whereas the mutant phenotype would be a white coat with black strips.
