摘要
本文研究了云南大理产的中国雨蛙的核型,并分析了4个地理居群中国雨蛙的核型.结果表明,不同地理居群具有相同的染色体数目和核型模式.即为2n=24,NF=48,核模式6+6.但中国雨蛙不同居群之间在SM数目和顺序、次缢痕或随体的位置等都有所不同,说明不同地理居群的中国雨蛙的染色体具有丰富的多样性.
The karyotypes of Hyla chinensis from Dali and Wenzhou were studied. The karyotypes of four populations of Hyla chinensis from different geographical regions were compared. The results demonstrated that the same species of different geographical populations have the same amount of chromosome and karyo-typic formulae. Hyla chinensis has 2n=24, NF=48 and 6+6 karyotypic formulae. But some dissimilarities were found among them. First,the number and sequence of submetacentric chromosome were different among them, and then the secondary contriction (SC) or satellite (Sat) were also different. It showed that the chromosomes of Hyla chinensis of different geographical population have diversities.
