Abstract

The population genetic structure of sand crab, Ovalipes punctatus in the East China Sea and the Yellow Sea was analyzed using amplified fragment length polymorphism (AFLP). A total of 196 loci were detected by four primer combinations among 95 individuals collected from five locations, 117 of which were polymorphic (59.69%). The proportion of polymorphic loci and Nei’s genetic distances for five populations ranged from 23.15 - 53.49%, and from 0.0029 - 0.0138, respectively. AMOVA analysis and pairwise FST revealed significant genetic differentiation among five samples, supporting that there are separate populations of this species. The pattern of isolation by distance indicated that the significant genetic differentiation observed between localities of O. punctatus was mainly due to the geographic distance.

 

Key words: Ovalipes punctatus, AFLP, genetic structure.
