Chinese. 采用外周血淋巴细胞培养及染色体分带技术,分析了海门白山羊的染色体核型与C-带。结果表明，海门白山羊二倍体染色体数为2n=60，常染色体和X染色体均为端部着丝粒染色体，X染色体的大小介于1号和2号染色体之间，Y染色体最小，为中部着丝粒染色体，公羊型 为60,XY，母羊为60,XX。大部分常染色体和X,Y染色体着丝粒部位显示阳性C-带,但不同染色体的阳性C-带区域大小不同。

The results showed that the diploid chromosome number of Haimen White goat breed was 2n=60.The autosomes and the X chromosome were telocentric chromosomes. The size of X chromosome was between No.1 and No.2 chromosomes. The Y chromosome was the smallest metacentric chromosome. The karyotype of buck was 60,XY and the karyotype of ewe was 60,XX.C-bands of most autosomal and X-chromosome，Y-chromosome were exclusively centromerically located, but the size of C-banded region was different among different chromosomes.
