Sixteen polymorphic microsatellite markers for the mud snail, Bullacta exarata (Philippi, 1848)

Sixteen polymorphic microsatellite markers were developed from a partial genomic library enriched using AG and AC repeats in mud snail (Bullacta exarata). Polymorphism of these loci was screened using 48 adult individuals of B. exarata. The number of alleles per locus ranged from 2 to 13. The observed and expected heterozygosities ranged from 0.5106 to 0.8125 and from 0.4868 to 0.9208, respectively. One locus departed significantly from Hardy–Weinberg equilibrium after Bonferroni correction. No linkage disequilibrium was found between any pair of loci. These polymorphic microsatellite markers are expected to provide valuable genetic information in population structure and genetic diversity, which will certainly facilitate management strategies of the mud snail.
