SNP array - Wikipedia
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.

Today SNP arrays capable of detecting >1M different human SNPs are available from both vendors. Call rates (the fraction of SNPs on the array that can be reliable called) and reproducibility of SNP calls exceed 99.5%.
Single-nucleotide polymorphism - Wikipedia
In genetics and bioinformatics, a single-nucleotide polymorphism (SNP / snɪp /; plural SNPs / snɪps /) is a germline substitution of a single nucleotide at a specific position in the genome.
Single-nucleotide polymorphism (SNP) microarrays have found significant clinical utility over the past decade for the detection of both constitutional and somatic cytogenetic abnormalities. SNP arrays contain probes that identify the genotype of a SNPs throughout the genome.
SNP Array— High Throughput SNP Genotyping Technique
2020年7月27日 · SNP array is an efficient microarray-based genotyping technique used for genome-wide screening of alterations. It can screen thousands of polymorphisms in a single run with a resolution of 10KB. In this article, I will explain the principle, process, advantages and applications of the SNP array. Stay tuned.
