摘要: 采用骨髓细胞染色体直接制片法,以及染色体G-分带和银染技术,对日本大耳白兔的染色体进行了研究。结果表明,日本大耳白兔核型为:2n=44,18m+7sm+10st+9t;染色体G-带型与文献报道基本一致;银染核仁组成区定位于12、14和20号染色体的短臂端部,单个细胞染色体银染颗粒范围为1~6个,平均2.93个。

Abstract: The karyotype, G-banding pattern and Ag-NORs pattern of the chromosomes of Japanese White Rabbit were studied. Its karyotype was 2 n=44.18 m+7sm + 10st+9t. The polymorphism of Ag-NORs was found in the chromosomes of Japanese White Rabbit.The number of Ag-NORs of chromosomes in one cell ranged 1~6 and averaged 2.93. The Ag-NORs were located on the terminals of the short arms of No. 12, 14 and 20 chromosomes. The G-banding pattern coincided generally with other reports.
