摘要
以岩牡蛎Crassostrea nippona面盘幼虫为材料,对岩牡蛎的核型进行了分析。结果显示,其染色体数为2n=20,染色体的总臂数为NF=40,全部为中部着丝粒染色体,无端部、亚端部以及亚中部着丝粒染色体,也无异形染色体出现,与大多数巨蛎属牡蛎的染色体核型相似。
The metaphase chromosome was prepared from velum larvae of oyster Crassostrea nippona. The karyotype analysis showed that chromosome number was 2n = 20 and karyotype formula 2n = 20m, NF = 40. There was no telocentric, subtelocentric and submetacentric chromosomes and polymorphism of the karyotype was not found, similar to most species in genus Crassostrea.
