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。
he karyotype, G-banding Pattern and Ag-NORs pattern of the chromosomes of Japanese White Rabbit were studied. Its karyotype was 2n = 44,18 m + 7 sm + 10 st + 9 t.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 2.98. The Ag-NORs,were located on the terminals of the short arms or No. 12, 14 and 120 chromosomes, The G-banding pattern coincided generally with other reports.
