SNP Arrays for Species Identification in Salmonids.

The use of SNP genotyping microarrays, developed in one species to analyze a closely related species for which genomic sequence information is scarce, enables the rapid development of a genomic resource (SNP information) without the need to develop new species-specific markers. Using large numbers of microarray SNPs offers the best chance to detect informative markers in nontarget species, markers that can very often be assayed using a lower throughput platform as is described in this paper.
