| Chromosome staining/banding/FISH |
Conspicuous heterochromatic blocks were observed in the pericentromeric regions of the chromosomes. Ag-NOR sites were identified interstitially on 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 located in interstitial position and colocalized with the 18S rDNA sites on the long arm of pair 22. |
