Is There More to SNP Chips than Just SNPs? Detecting Copy Number Variation in Chickens

SNP chips can be used to provide genomic information on copy number variations (CNV) in addition to information on the SNPs (single nucleotide polymorphism) for which they were originally designed. Although some CNVs may be missed compared to methods specifically designed for CVN detection, CNVs derived from SNP chips can contribute valuable information on additional genetic variation without additional cost.
