The intraspecific biochemical-genetic variation of 40 presumptive stru
ctural loci in examples of Gunthers's vole (Microtus guentheri) from E
urope were studied. Its allozyme divergence is studied based on the mo
st common European voles, Microtus arvalis and Microtus nivalis. The d
etermined genetic between these three species is in accordance with th
e taxonomic classification of these species into two separate subgener
a.
