| 摘 要： | 腹斑倭蛙：2n=26(16M 1-SM),NF=52,除Nos,2,3,4,6,9等五对为SM外，其余诸对均为M，次缢痕位于8q，威宁蛙2n=26(18M 8SM),NF=52,除Mos,3,4,6,7 等四对为SM外，其余各对为M，次缢痕出现在1q和7q两处，前者频率较高，根据相对长度，臂比值和次缢痕的位置和数目讨论了蛙亚科的核型演化机制，推断可能是相互易位和臂间倒位为主。

| Abstract: | The karyotypes of two frog species (Rana weiningensis and Nanorana ventripunctata) were reported here. For N. ventripunctata 2n = 26 (16 M+10 SM) , NF = 52, NOS. 2, 3, 4, 6, 9 are SM, the secondary constriction located on 8 q. And 2n = 26 (18M+8SM), NF = 52, NOS. 3. 4, 6, 7 are SM and the secondary constriction is on 1 q and 7 q in R. weiningensis. Finally the karyotypic evolution mechanism for subfamily of Raninae based on the relative length, arm ratio and the location of secondary constriction is discussed. |
