| Chromosome staining/banding/FISH | Multiple AgNORs found with inter-individual variation in both stocks terminally located in long arm of pair 6, short arm in one of chromosome pair 14 and pair 19 in Pindorama stock; terminally located on long arm in one of chromosome pair 6, and short arm in one of chromosome pair 14 and 19 in Lopei stock. C-band showed pericentrometric bands & associated with AgNORs in both stocks, found in pairs 5, 7, 9, 10, 16, 19, 24 in Pindorama stock, but in pairs 4, 5, 8, 10, 16, 19, 21, 22, 25 in Lopei. |
