A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed. A genetic marker may be a short DNA sequence, such as a sequence surrounding a single base-pair change (single nucleotide polymorphism, SNP), or a long one, like minisatellites. Web12.9 - Statistical Testing in GWAS. In GWAS studies, usually a test is done for every gene. Several tests are available. In the simplest case, we have a categorical phenotype with two categories.
