【摘要】 本文通过对二狼山、阿尔巴斯、辽宁和大青山白绒山羊染色体组型的分析研究，首次证实了内蒙古白绒山羊类型不同，各染色体之间存在着共同的特点即染色体形态均为端着丝点，染色体数目均为２ｎ＝６０；但各染色体之间的相对长度存在着极显著差异，即绒山羊品种不同，染色体相对长度不同。这一研究结果为今后不同类型绒山羊互相辨别提供了依据，为今后内蒙古绒山羊选育提供了理论依据。更多还原

【Abstract】 Through the study on the karyotype of white cashmere goat from Er-lang Mountain,Alps, Liao-ning and Danqing Mountain, it was prived for the first time that the type of white cashmere goat in Inner Mongolia was different. Their chromosomes have the same feature, all their chromosomes states are arcocentric and all their chromosome numbers are 2n=60,but the relative length of their chromosomes is significantly different for different cashmere goat type, the relative length of chromosome is different.These results provide the basis both for the identification of different cashmere goats and the selection and rearing of cashmere goat.更多还原
