| Abstract: | The Karyotype of Kaloula pulchra pulchra was examined by using metaphase of bone marrow cell. The diploid chromosomes number of Kaloula pulchra pulchra is 28 2n=28,According to their size,shape and the position of contromere,28 chromosomes are tentatively classifi- ed into 4 group.The same secondary constrictions were found when the male or female chromosomes were observed.To compare the Karyotypes of Kaloula pulchra pulchra with Kaloula borealis,the chromosome number of both are 2n=28.All of the chromosomes in Kaloula pulchra pulchra are alike to those on Kaloula borealis There is no visible evidence of sex chromosome dimorphism. |
