Abstract
A novel polymorphism of nucleolar organizer regions (NORs) and complex inversion chromosome 8 of the white-handed gibbon (Hylobates lar) in Thailand was found after standard whole blood lymphocyte culture and G-banding technique were applied to stain the chromosomes. The results showed that 2n of H. lar was 44. The type of autosomes were 28 metacentric, 12 submetacentric and 2 acrocentric chromosomes, with the X and Y-chromosome being submetacentric and acrocentric chromosome, respectively. In addition, a pair of the long arm of chromosome 13 showed clearly observable NORs. This is the first report on polymorphism of NORs in H. lar. The result indicated the presence of heteromorphism of chromosome 13 (13a13b) in female; NORs were found in 13a and not in 13b. There is homomorphism of chromosome 13 (13a13a) in male, there are NORs in both chromosomes. We also found the complex inversion chromosome 8 that presence homomorphism (8b8b) in both male and female.
