Heterochromatin distributed over pericentromeric regions of most chromosomes and telomeric regions on short arms of pair 14. Ag-NORs located at terminal position on short arms of pair 14, interspersed with GC-rich heterochromatin segments positively stained by chromomycin A3. 18S rDNA location was overlapping with Ag-NORs. 5S rRNA genes located at interstitial region on chromosome pair 23. |
