【摘要】 采用外周血淋巴细胞培养法研究了贵州黑山羊、贵州白山羊的染色体核型及Ｃ－带的多态性。结果表明２个品种的染色体数均为２ｎ＝６０；雌性性染色体为ＸＸ、雄性为ＸＹ。除Ｙ染色体外，全组均为端着丝粒染色体。贵州黑山羊染色体组中第８对染色体的一条显示深染，表现出遗传的多态性。更多还原

【Abstract】 The karyotypes,the chromosome number and C-banded of Guizhou black goat and white goat have been studied,using a method of peripheral blood in culture.The diploid chromosome number of both samples of Guizhou goat breeds are 60, sex chromosome in male and female are XY and XX respectively.All of the chromosome in gemoe,expect Y of them,are telochromosomes. One chromotid in the homologous chromosome pair 8 was stained darkly with Giemsa at the end of arm,it showed certain polymorphism in C-banded.更多还原
