Single nucleotide polymorphisms (SNPs) are point mutations with biological significance across diverse scientific disciplines ranging from medicine to agriculture. SNPs are useful in predicting the disposition for some diseases [1], [2], as indicators for the genetic basis for varying responses to pharmacological drug treatment [3], for classifying bacterial populations into specific genetic groups [4], [5], and for association with specific phenotypic traits, such as insecticide resistance in insects [6]. Technologies that permit cost-effective yet expeditious SNP interrogation are in demand.
