九龙牦牛高分辨G带带型的研究

Study on the Pattern of High Resolution Chromosome G—band of Yak in Jiulong County

采用氨甲喋吟阻断法使细胞分裂同步化,并结合胰酶 G 显带技术,研究了九龙牦牛的高分辨 G 带核型。将九龙牦牛显带染色体划分为108个区。

Using methotrexate treatment to induce synchronous division combined with GTG technique,the high resolution banded chromosomes of Jiulong Yak were investigated.The banded chromosomes were divided into 108 regions.
