中国海区与日本海区皱纹盘鲍染色体核型的比较研究

Comparative Studies on Karyotype of Haliotis discus hannai Ino between China and Japan

以中国海区皱纹盘鲍和日本海区皱纹盘鲍鳃组织为实验材料,经空气干燥法进行染色体制片,对2个地理居群皱纹盘鲍的核型分析结果表明,中国海区皱纹盘鲍与日本海区皱纹盘鲍的核型相同,核型公式均为2n=36=22m+14sm,NF=72。2个地理居群皱纹盘鲍间不存在核型多型现象。

The gill cells of Haliotis discus hannai in China and Japan were used for karyotype analysis by air drying method.The results show that the karyotype of both populations is the same as 2n=36=22m+14sm,NF=72.There is no difference in the karyotype of two populations.
