In molecular biology, SNP array is a type of DNA 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 type of variation in the genome. Around 335 million SNPs have been identified in the human genome, 15 million of which are present at frequencies of 1% or higher across different populations worldwide. WebJul 28, 2024 · By using small, well-defined probes rather than banding patterns and microscopes, microarrays can detect differences as small as 500 kilobases, several orders of magnitude smaller than the limit for traditional karyotyping, revealing microdeletions and microduplications that can cause illness and that are not visible with G-banding. finney-smith mavs
