|
| Number of specimens with sex | 10 (5 male, 5 female) |
|
| Diploid chromosome number | 48 |
|
| Karyotype formula | 1m+1sm+1st+21a |
|
| Fundamental arm number | 52 |

|
| Chromosome staining/banding/FISH | C-bands localized in and around centromeric regions of 7 acrocentric chromosome pairs (i.e. 4, 5, 6, 12, 13, 15 and 16). One acrocentric chromosome pair (15) showed an identifiable C-band in telomeric region of long arm. One telocentric chromosome pair showed intensive AgNOR region at terminal. |
