摘要
应用IBAS-2000图象分析系统对鲢(Hypophthalmichthysmolttrix)染色体进行自动核型分析,获得比较准确的鲢染色体相对长度、臂比、着丝点指数数据和核型标准图象信息。染色体组型2n=48,核型公式18m+22sm+8st,总臂数(NF)为88。与常规方法比较,该方法重现性好,准确性高,速度快,图形和数据能永久保存,便于建立鱼类染色体标准图形信息库。
Silver carp(Hypopthalmichthys molitrix ) chromosomes were analysed withIBAS─2000 image analysis system , and more accurate data of relative length , arm ratio,centric index and karyogram were obtained. There is a diploid chromosome number of 48 insilver carp ,the karyotype which consists of 9 pairs of median ,11 pairs of submedian and 4pairs of subterminal centric chromosomes with a total number of chromosome arms amountsto 88.In comparison with the conventional methods ,this one is highspeed and moreaccurate,and the data and karyogram obtained can be stored permanently so as to establishadata base ofchromosomes in fish.
