以转铁蛋白及其同工酶为标记，研究了雌核发育银鲤4个无性系（A、D、E、F）的遗传多样性。五种蛋白质的调查，三（转铁蛋白，酯酶和超氧化物歧化酶）表示多态性和8个多态位点检测。这些位点可能由共显性等位基因编码，并分析了它们的遗传方式。克隆内同质性和克隆间异质性的观察，这使我们能够推断它们之间的克隆性质和进化关系。中国银鲫种群的克隆多样性也与德国雌核发育鲫的数据进行了比较。
Genetic diversity among four clones (A, D, E, F) of gynogenetic silver crucian carp was studied using transferrin and isozymes in the blood as markers. Of the five proteins investigated, three (transferrin, esterase and superoxide dismutase) indicated polymorphism and eight polymorphic loci were detected. These loci were probably encoded by codominant alleles and their inheritance patterns were analyzed. Intraclonal homogeneity and interclonal heterogeneity were observed in these clones, which allowed us to infer the clonal nature and evolutionary relationship between them. Clonal diversity in this population of silver crucian carp in China was also compared with data reported from gynogenetic crucian carp in Germany.
