摘要/Abstract

摘要： 　　目的：探讨γ拟钉螺分类演化的遗传学基础。方法：用微量平面淀粉胶电泳法，检测浙江省开化及淳安县６个螺群宋氏γ拟钉螺和１个螺群中国γ拟钉螺的２４种等位基因酶谱。结果：共测得２９个位点，宋氏γ拟钉螺多态位点所占比例为６．９％－１３．８％；中国γ拟钉螺全部为单态位点。宋氏γ拟钉螺的种内Ｎｅｉ氏遗传距离（Ｎｅｉ＇ｓＤ）小于０．１２；但宋氏γ拟钉螺与中国γ拟钉螺两者种间Ｎｅｉ＇ｓＤ为０．７３。结论：在等位基因水平显示γ拟钉螺种内变异不明显，种间差异显著。

Abstract: 　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.

Key words: Gammatricula songi, Gammatricula chinensis, allozyme zymogram, genetic distance
