| 摘 要： | 采用骨髓细胞蒸汽固定法对采自河南的3种隆肛蛙进行核型研究,均为2n=26,NF=52.隆肛蛙(Feirana quadrana)栾川居群Nos.2,3,6为sm,10 p出现次缢痕;太行隆肛蛙(F.taihangnicus)Nos.2,3,4为sm,9p上出现次缢痕;叶氏隆肛蛙(F.yei)Nos.2,3,9为sm,次缢痕位于6 p.3种隆肛蛙核型差异显著.通过比较发现,隆肛蛙不同地理居群的sm数目和顺序、次缢痕的位置有明显差别,出现了明显的遗传分化.

| Abstract: | The karyotype of three species,genus Feirana,from Henan Province,China,studied using the bone marrow comparing.The results indicated that three species had a karyotype of 2n=26,NF=52,with five larger and eight smaller chromosome pairs,but differed notably in the sequence of the submetacentric chromosome,secondary constriction(SC) or the satellite.Nos.2,3,6 are SM,SC on 10 p in F.quadrana.Nos.2,3,4 are SM,SC on 9 p in F.taihangnicus.Nos.2,3,9 are SM,SC on 6 p in F.yei.The karyotype of three different geographical populations of F.quadrana were compared.They differed in the number and sequence of the submetacentric chromosome,secondary constriction.Nos.2,4 are SM,SC on 12 p for Anxian population,Sichuan Province.Nos.2,3,6,7 are SM,SC on 10 p for Wushan population,Chongqing City.Nos.2,3,6 are SM,SC on 10 p for Luanchuan population,Henan Province. |
