The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.
刺鳅,属鲈形目、刺鳅科(Perciformes,Mastacembelidae),是广泛分布于中国南方的小型淡水鱼类。1998年,我室通过核型分析,首次发现该物种具有明显分化的异形性染色体,其性别决定类型为XX/XY型。1999年,本室通过染色体显带、精母细胞联会复合体观察,再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体,两者不仅已经出现结构异染色质分布上的不同,同时在外部形态上也存在明显差异,识别特征鲜明,在光镜观察下无需显带即能清晰辨认性染色体。
