Abstract: | We describe 27 single nucleotide polymorphisms (SNPs) in a commercially important bivalve, the weathervane scallop (Patinopecten caurinus), identified using a targeted‐gene approach. We further characterize 12 of these using 5′‐nuclease and allele‐specific PCR assays. Polymorphisms were identified in both mitochondrial and nuclear genes. These are the first SNPs developed for delineating population structure in the weathervane scallop and will provide a useful complement to currently available genetic markers. |
