    Abstract:

    Objective To analyze the phylogenetic relationship among four groups of Microtus fortis by gene distribution characteristics of ten biochemical loci.Method Ten isozymes and proteins of Microtus fortis were investigated by cellulose acetate membrane electrophoresis.Result and Conclusion The electrophoretic patterns of the small voles from Heilongjiang province revealed great divergence in comparison with the other three groups.The small voles from Heilongjiang had their particular alleles at six loci and the phenotypes of them were completely different at three of these loci.The genetic distances among the voles from Hunan,Ningxia and the big voles from Heilongjiang ranged from 0.0633 to 0.2107,while that between the small voles from Heilongjiang and the other three groups ranged from 0.7068 to 0.8953.The phylogenetic tree constructed by UPGMA showed that the voles from Hunan,Ningxia and the big voles from Heilongjiang could be gathered into one group,but the small voles from Heilongjiang were in another group alone.Those results indicated that the phylogenetic relationship among the voles from Hunan,Ningxia and the big voles from Heilongjiang is closer than that between them and the small voles from Heilongjiang.
