The karyotype represents the basic genetic make-up of a eukaryotic species. Comparative cytogenetic analysis of related species based on individually identified chromosomes has been conducted in only ...
Karyotype Analysis of Lablab purpureus (L.) Sweet Using Fluorochrome Banding and Fluorescence in situ Hybridisation with rDNA Probes
combined PI and DAPI staining FISH hyacinth bean karyotyping ribosomal gene
2015/10/9
The mitotic chromosomes of Lablab purpureus (L.) Sweet were characterised using sequential combined propidium iodide (PI) and 4',6-diamidino-2-phenylindole (DAPI) (CPD) staining and fluorescence in si...
In this study, morphology of chromosomes was determined via karyotype and idiogram analysis in Nutria 7272 line of hexaploid (2n=42) triticale obtained from CIMMYT. On the bases of the presence or abs...
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...
