三种壁虎染色体核仁组织者的银染色观察与蹼壁虎的核型Observation on the Ag-NORs in 3 Species of Gekko and the Karyotype of G.swinhonis
无蹼壁虎 铅山壁虎 多疣壁虎 核仁组织者 核型
2008/1/29
摘要本文以骨髓细胞为材料, 采用常规制片法和一步银染色技术,首次报道了无蹼壁虎、铅山壁虎和多疣壁虑的NORs,并用α-巯基乙醇短期培养无蹼壁虎的骨髓细胞,分析其核型。结果表明,3种壁虎都仅显示一对NORs,也未见有融合现象。其中无蹼壁虎的NORs位于第18对染色体的次缢痕区,而铅山壁虎和多疣壁虎分别位于第19对和第14对上。另外,我们从C带分析中发现,铅山壁虎和多疣壁虎的NORs位点均为结构异染色...
摘要应用常规方法获得了杂种猪( 野猪（♂）×家猪（♀）)的核型、C带和174条带纹的G带，应用微量秋水仙素法得到了258条带纹的高分辨G带。结果表明，杂种猪的二倍体细胞染色体数目2n=38，C带具有多态性，G带和高分辨G带与家猪相比无明显差异，它们属于同一种。

摘要
为了从选种、杂交改良、疾病诊断以及性别决定的遗传机制等方面为羊驼的繁育与推广提供更为有效的细胞遗传学资料，本试验采用外周血淋巴细胞培养法及胰酶-EDTA法分析了23只胡阿基亚型羊驼（Huacaya alpaca，雌20只，雄3只）的染色体核型及其G-分带，结果表明：羊驼二倍体染色体数目为2n=74，雄性羊驼核型为74，XY；雌性羊驼核型为74，XX。其中，1～20对常染色体为亚端着丝粒染色...
摘要采用外周血淋巴细胞培养--空气干燥法，对泰和乌骨鸡染色体核型和带型进行了研究。结果表明：泰和乌骨鸡体细胞染色体数目2n=78,染色体基本臂数AF=90，1、9号染色体及Z、W性染色体为中央着丝粒（m）染色体，2、4、7号染色体为亚中央着丝粒（sm）染色体，3、6、8、10号染色体为端着丝粒（t）染色体。G带研究表明：前10对大型染色体可分为29个区，190条带。C带处理发现，所有母鸡分裂相中W...

2007/12/7
摘要以骨髓细胞为材料研究了棕黑锦蛇赤峰亚种的染色体, 结果表明,该物种的2n=36,由8对大型的和10对微小的染色体组成,AF=50。No.4为性染色体(ZW型);所有大型染色体均显示端粒深染C带,但仅NO.2、3、5和Z染色体显示着丝粒浅染C带。W染色体为整条C带阳性;该物种一对NOR分布于微小染色体。锦蛇属核型可能经历过染色体间的着丝粒融合的罗伯逊易位。
