The relationship between mutations and polymorphisms

While a mutation is defined as any alteration in the DNA sequence, biologists use the term „single nucleotide polymorphism” (SNP) to refer to a single base pair alteration that is common in the population. Specifically, a polymorphism is any genetic location, at which at least two different sequences are found, with each sequence present in at least 1% of the population. Note that the term “polymorphism” is generally used to refer to a normal variation, or one that does not directly cause disease. Moreover, the cutoff of at least 1% prevalence for a variation to be classified as a polymorphism is somewhat arbitrary; if the frequency is lower than this, the allele is typically regarded as a mutation.
