摘要
运用改进的鸡外周血淋巴细胞培养———空气干燥法,分析了仙居鸡染色体G带和Ag NORs。G带研究结果表明:前10对大型染色体可分为30个区,144条带,同时对G带带型特征进行了具体描述,并绘制了G带模式图。Ag NORs处理发现:仙居鸡的Ag NORs常分布于1p、3p、4p、Zp、2q上,均数为3.26,众数为3。不同个体间以及同一个体的不同细胞间Ag NORs数目存在多态性;此外研究还发现Ag NORs联合现象。
In this study, the chromosome slides were made by improved peripheral blood lymphocyte culture- drying naturally method, and analyzed G- band patterns, Ag- NORs patterns of Xianju chickens. The results were as follow: Xianju chickens' G- band of the first ten pairs chromosomes was divided into 30 (regions) and 144 bands, its character was described and its idiogram was depicted. Xianju chickens' Ag- NORs were located on 1p, 3p, 4p, Zp and 2q, the mean value per cell was 3.26 and the mode was 3. The size, number and distribution between different individuals and of the same individual were polymorphic and associations of Ag- NORs were found .
