SNP
Single-nucleotide polymorphisms, also known as SNP's (prounced 'snip') is a type of genetic variation that occurs within a population of an organism.
When a nucleotide pair differs, within a population, at a particular site on the DNA this is known as SNP. An example of this is if at a particular nucleotide site some DNA molecules have a T-A base pair. However in the same population, other DNA molecules might have a G-C base pair at the same nucleotide site.[1] This is an SNP.
