Development and characterization of 108 SNP markers in the Iwagaki oyster, Crassostrea nippona

A total of 108 single nucleotide polymorphism (SNP) markers from the Iwagaki oyster, Crassostrea nippona were isolated and characterized based on high-throughput sequencing in this study. The minor allele frequency per locus ranged from 0.0167 to 0.4844. The observed heterozygosity and expected heterozygosity varied from 0 to 0.9688 and 0.0333 to 0.5079, respectively. Eighteen loci showed significant deviation from Hardy-Weinberg equilibrium. These SNP markers described in this study will provide a valuable tool for population genetic analysis and natural resource conservation of C. nippona.
