A single-nucleotide polymorphism, often abbreviated to SNP (/ËsnÉªp/; plural /ËsnÉªps/), is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).
Definition of a Single Nucleotide Polymorphism, SNP. A SNP is a site in the DNA where different chromosomes differ in the base they have. For example, 30 percent of the chromosomes may have an A, and 70 percent may have a G. These two forms, A and G, are called variants or alleles of that SNP.
