[Studies on allozyme of Gammatricula]
1Institute of Parasitic Diseases, Zhejiang Academy of Medical Sciences, Hangzhou 310013.
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.
