| Chromosome staining/banding/FISH |
Dark Ag-NOR bands signals observed on short arm subtelomeric of acrocentric chromosome pair 13 in both males and females. Three NOR polymorphism patterns found: 1) homomorphic that shows an equal size of both chromosome pair 13 (13a13a), 2) heteromorphic that displays different sizes of NORs of chromosome pair 13 (13a13c) and 3) heteromorphic that found only in one homologous chromosome pair 13 (13a13b). |
