云南产大绿臭蛙(Odorrana livida)的染色体核型研究

A study on the karyotype of Yunnan large odorous frog (Odorrana livida)

研究了云南勐腊县产的大绿臭蛙的核型,核型模式为2n=26(18M+8SM),5+8,NF=5;并与已报道的安徽黄山和香港的大绿臭蛙的核型进行了比较.结果表明虽然大绿臭蛙的不同地理种群之间的核型模式相同,但在SM和M的数目、顺序以及次缢痕的位置等有所不同,说明大绿臭蛙的不同地理种群的染色体具有丰富的多样性.

The karyotype of large odorous frog(Odorrana livida) collected from Yunnan Mengla has been studied.The karyotypic formulae of Odorrana livida is 2n=26(18M+8SM),5+8,NF=5.The karyotypes of three populations of Odorrana livida from different geographical regions are compared.The results demonstrate that Odorrana livida of different geographical populations have the same amount of chromosome and karyotypic formulae.But some dissimilarities are found among them.First,the number and sequemce of submetacentric chr...
