八种鱼类(鲤属和白鱼属)的染色体组型研究
Studies of The Karyotypes of Eight Species of Fishes in Cyprinus and Anabarilius
-
摘要: 本篇报导了四种鲤属鱼和四种白鱼属的染色体组型研究结果,并从细胞遗传学角度讨论了这些鱼类的物种形成问题,同时提出了这样一种看法:用所研究过的五种鲤属鱼类进行种间杂交,获得能育后代的可能性较大。Abstract: By the methods described in a previous paper,we have studied the karyotypes of eight species of fishes in Cyprinus and Anabarilius,I.e.C.(Cyp.) longipectoralis C.(Cyp.) megalophthalmus,C.(Cyp.) pellegrini barbatus,C.(Nesocyp.) micristius fuxianensis,A.andersoni,A.macrolepis,A.grahami,as well as A.alburnops taken from Kunming lake and A.alburnops taken from Qilu lake and discussed the genetic and cytogenetic causes of speciation in these fishes.
