| Chromosome staining/banding/FISH |
Conspicuous heterochromatic blocks were observed in the pericentromeric regions of the chromosomes. Ag-NOR sites were identified on terminal position chromosome pair 22. FISH with telomeric probes showed markings exclusively in the terminal regions of almost all the chromosomes. Mapping of 5S rDNA subunits showed single sites in the terminal position of the short arms on pair 6. |
