Abstract: Genetic diversity and population structure of six populations of commercially important whelk, B. zeylanica from Southeast coast of India were studied. A total of 187 individuals were genotyped at 12 loci and differences in the genetic diversity between populations were correlated with known population histories. Study identified 475 alleles and all the studied loci were highly polymorphic. The number of alleles ranged between 4 and 12 with a global mean of 6.597. Global mean of observed and expected heterozygosities were 0.547 and 0.794 respectively. Within population inbreeding estimate (FIS) value (0.311) indicated shortfall of heterozygosity in the populations. Microsatellite analysis revealed less genetic diversity in all studied genetic groups. Analysis of Molecular Variance (AMOVA) showed that 4% of the total variation was due to differences between genetic groups.
