Line 1: {{~~mergeto~~Mergeto\|DNA microarray\|date=October 2006}} A '''SNP array''' is a type of [[microarray]] which is used to detect [[polymorphisms]] within a population. A [[single nucleotide polymorphism]] (SNP), a variation at a single site in DNA, is the most frequent variation in the genome, there are about 5-10 million SNPs in the human genome. As SNPs are highly conserved throughout evolution and within population, the map of SNPs serves as an excellent genotypic marker for research.
