| Chromosome staining/banding/FISH |
C-bands localized in and around centromeric regions of 7 acrocentric chromosome pairs (i.e. 4, 5, 6, 12, 13, 15 and 16). One acrocentric chromosome pair (15) showed an identifiable C-band in telomeric region of long arm. One telocentric chromosome pair showed intensive AgNOR region at terminal. |
