[High resolution GTG banding and nucleolus organizer regions of chromosomes from the vole Microtus kirgisorum].

The use of GTG-banding of chromosomes in combination with the pipette method of chromosome preparation at the early metaphase made it possible to distinguish about 520 segments in the haploid chromosome set of vole Microtus kirgisorum. The ideogram of M. kirgisorum chromosomes was obtained on the basis of detailed investigation of chromosomes at different condensation levels. Data of the localization and the number of nucleolus-organizer regions are given.
