| Chromosome staining/banding/FISH | Heterochromatic blocks on short arms of pairs 10 and 24 and less evident bands at centromeric regions of other chromosomes. AgNOR located at interstitial region on long arms of sm chromosomal pair 10. FISH with 18S and 5S rDNA probes revealed independent chromosomal signals localization, the 18S located at interstitial region on long arms of sm pair 10 and 5S rDNA located at interstitial region on long arms of pair 24. |
