The diploid chromosome number of Oriental vole is 56, and all chromosome in the complement are acrocentrics. The Y chromosome is the smallest one.
The C-banded karyotype reveals that the centromeric C-bands are abundant, and all chromosomes are C-bands positive, and Y chromosome is completely heterochromatin.
The silver-stained karyotype has been studied. Five pairs of Ag-NORs were found in the terminal of Nos. 1, 2, 6, 14, 27, respectively, and the heteromorphism and association of Ag-NORs were also observed.
