Isolation and characterization of polymorphic microsatellite markers in the red snow crab ( Chionoecetes japonicus).

A total of 12 polymorphic microsatellite DNA loci were isolated from the red snow crab, Chionoecetes japonicus (Brachyura: Majidae), one of important fisheries resources in the Far East. The number of alleles observed at each locus ranged from two to 19, with the observed and expected heterozygosities of 0.125–0.875 and 0.156–0.949, respectively, suggesting these loci to be a useful molecular marker for population analysis in this species. Of the 12 loci, seven also were available for genotyping of the snow crab, Chionoecetes opilio, implying these loci as a useful molecular marker in the genus Chionoecetes. [ABSTRACT FROM AUTHOR]
