Using the methods of classical shape size measuring and chromosome analysis, we studied the morphological characters and Karyotype of Cobitis sinensis in Xiangjiang River. We also investigated the evolution line and Karyotype polymorphism of the C . sinensis by the methods of cytological classification and cytocatalytic. Our results suggest that the formation of chromosome polymorphism was concerned with heterologous hybridization and some of C . sinensis may perpetuate in a clonal manner by natural gynogenesis.

本文以湘江流域的中华花鳅为研究对象，运用经典的形态测量观察方法、染色体制片技术对中华花鳅的形态生态特征、染色体组型进行了初步研究：运用细胞分类和进化方法对中华花鳅的核型演化和核型多态现象的形成进行了分析，提出：其核型多态的形成牵涉到鳅科鱼类的异源杂交，某些中华花鳅可能是行雌核发育生殖的。

文章摘要：为了分析外源基因在转基因鱼F1中的遗传特征和规律，采用PCR检测技术对Hu-IFN-α基因在转基因草鱼及其杂交F1，雌核发育F1中的遗传表达情况进行检测。

The study indicated that RAPD technique is useful and practical for the identification between gynogenesis fish and hybrid individuals.RAPD and AFLP technique were used to screen the sex-related DNA marker through analyzing the DNA differences between female and male of Jian carp.

通过对反应条件的优化处理，在引物E-ACG／M-CAA的扩增图谱中找到一条雌性特异的DNA条带，分子量约323bp，雄性个体均无此条带，初步发现了雌雄之间的遗传差异，可为建鲤遗传性别的鉴定提供参考；同时发现某些位点在雌性和雄性个体出现的比例存在很大差异，推测与遗传性别有一定的关联。

Diploid gynogenesis was induced by activating egg development with UV irradiated sperm (80 mJ/cm2, the homologous or the heterogenous sperm) for 5 min in seawater at 18 ℃, and then subjecting the eggs to cold shock in 3 ℃ seawater for 45 min.
