[A rare case of chromosome mutation in the ground vole Terricola majori (Arvicolinae, Rodentia)].
A rare case of chromosome variability is described for the ground vole, Terricola majori, from the Lagodekhi Nature Reserve (Georgia). This species is characterized by a stable karyotype (2n = 54, NF = 60), but we found an animal in which 2n = 53, NF = 60. The change in the diploid number resulted from a Robertsonian translocation accompanied by a local amplification of satellite sequences in centrometric heterochromatin. This structural rearrangement is probably a neutral mutation and is described for forest T. majori voles for the first time.
