| Source of chromosomes | Anterior kidney |
|
| Number of specimens with sex | 02 (02 females) |
|
| Diploid chromosome number | 68 |
|
| Karyotype formula | 12m+12sm+8st +36a |
|
| Fundamental arm number | 100 |

| Chromosome staining/banding/FISH | C-banding revealed few heterochromatic tags only in the centromeric and telomeric regions of some chromosomes. Ag-NORs were detected in up to five chromosomes with intraindividual variation. Double staining with CMA3/DAPI revealed five sites rich in GC coinciding with the Ag-NORs and confirmed by FISH with the 18S rDNA probe. |
