In genetics and bioinformatics, a single-nucleotide polymorphism (SNP / snɪp /; plural SNPs / snɪps /) is a germline substitution of a single nucleotide at a specific position in the genome.

Not all single-nucleotide changes are SNPs, though. To be classified as a SNP, two or more versions of a sequence must each be present in at least one percent of the general …
