摘要
本文研究了蛙属三种:脆皮蛙、长趾蛙和威宁蛙的染色体核型,结果表明均具有蛙属典型的核型:2n=26,由5对大染色体和8对小染色体组成。三种在臂比值和次缢痕的有无、位置方面存在差异。同源染色体对间未发现异形现象。
The karyotypes of three species of Rana （fragilis, macrodactyla and weiningensis） were studied. All the three species had the same diploid number of chromosomes, 2n=26 with 5 large and 8 samll pairs. Differences occured in arm ratio and secondary constriction. No heteromorphic chromosomes were found in the three species.
