In the field of genetic sequencing, genotyping by sequencing, also called GBS, is a method to discover single nucleotide polymorphisms (SNP) in order to perform genotyping studies, such as genome-wide association studies (GWAS). GBS uses restriction enzymes to reduce genome complexity and genotype multiple DNA samples. After digestion, PCR is performed to increase fragments pool and then GBS libraries are sequenced using next generation sequencing technologies, usually resulting in about 100bp single-end reads. It is relatively inexpensive and has been used in plant breeding. Although GBS presents an approach similar to restriction-site-associated DNA sequencing (RAD-seq) method, they differ in some substantial ways.
