AB  - We explored the topology of 18S and 28S rDNA units by fluorescence in situ 
      hybridization (FISH) in the karyotypes of thirteen species representatives from 
      major groups of Primates and Tupaia minor (Gunther, 1876) (Scandentia), in order 
      to expand our knowledge of Primate genome reshuffling and to identify the 
      possible dispersion mechanisms of rDNA sequences. We documented that rDNA probe 
      signals were identified on one to six pairs of chromosomes, both acrocentric and 
      metacentric ones. In addition, we examined the potential homology of chromosomes 
      bearing rDNA genes across different species and in a wide phylogenetic 
      perspective, based on the DAPI-inverted pattern and their synteny to human. Our 
      analysis revealed an extensive variability in the topology of the rDNA signals 
      across studied species. In some cases, closely related species show signals on 
      homologous chromosomes, thus representing synapomorphies, while in other cases, 
      signal was detected on distinct chromosomes, leading to species specific 
      patterns. These results led us to support the hypothesis that different 
      mechanisms are responsible for the distribution of the ribosomal DNA cluster in 
      Primates.
