Researchers often look for genetic variations to better understand phenotypic traits. Within a genome differences may arise in numerous ways, including single nucleotide polymorphisms (SNPs), insertions or deletions (indels), or copy number variations (CNV). Genotyping techniques use polymerase chain reaction (PCR), often with a primer-pair and target-specific fluorescent probe in quantitative PCR (qPCR), a sensitive and specific way to detect SNPs.
