UC Davis

We characterized 37 new microsatellite markers in the Pacific lion-paw scallop (Nodipecten subnodosus) and tested for cross-amplification in four other species. Genetic diversity was estimated using 24 individuals from the Lagoon Ojo de Liebre, B.C.S., Mexico. Allelic richness varied from 5 to 27 alleles per locus and the average expected heterozygosity was 0.76. Ten loci exhibited significant departure from Hardy–Weinberg equilibrium likely due to the presence of null alleles. Sixteen of these markers cross-amplified in closely related N. nodosus, while little or no amplification was observed in three Argopecten species.
