02-11-2023-2107 - single-nucleotide polymorphism (SNP /snɪp/; plural SNPs /snɪps/)

In genetics, a single-nucleotide polymorphism (SNP /snɪp/; plural SNPs /snɪps/) is a germline substitution of a single nucleotide at a specific position in the genome and is present in a sufficiently large fraction of the population (1% or more). Single nucleotide substitutions with an allele frequency of less than 1% are called "single-nucleotide variants", not SNPs. ^{[1] [2][3][4]}
