九龙牦牛高分辨G带带型的研究

Study on High Resolution chromosome G-banding Pattern In Jiulong Yak

采用氨甲喋呤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。将牦牛显带染色体划分为１０８个区，并绘制了Ｇ带模式图。

Using methotrexate treatment to induce cell synchronous division,combined with GTG technique,the high resolution banded ehromosomes of Jiul-ong Yak were investigated.The banded chromosomes were divided into 108regions,and G-banding idiograms have been drawn.
