[Studies on allozyme of Gammatricula].

AIM

To furnish molecular genetic evidences for taxonomy of Gammatricula.

METHODS

A total of 24 enzymes of 6 populations of Gammatricula songi and 1 population of Gammatricula chinensis collected from Kaihua County and Chunan County of Zhejiang Province were studied using horizontal starch gel electrophoresis.

RESULTS

29 loci were found. The percentages of polymorphic loci of G. songi populations were 6.9%-13.8%. All loci of G. chinensis were monomorphic. The Nei's distance among G. songi populations did not exceed 0.12. The Nei's distance between G. songi and G. chinensis was 0.73.

CONCLUSION

The allozyme variations of inter-G. songi are limited, but the allozyme variation between G. songi and G. chinensis is significant.
