High resolution karyotype of thai crab-eating macaque (Macaca fascicularis)

Abstract

Comparative chromosome banding analysis and/or fluorescence in situ hybridization (FISH) studies are established approaches to compare human and ape chromosomes. FISH-banding is a relatively new and not routinely applied method suited very well to provide to a better understanding of the evolutionary history of primate and human phylogeny. Here multicolor banding (MCB) applying probes derived from Homo sapiens was used to analyze the chromosomes of Thai crab-eating macaque (Macaca fascicularis). The results agree with those of previous studies in other macaques, e.g. Macaca sylvanus or Macaca nemestrina. This result pinpoints, that morphological differences within the Ceropithecoidae must be founded rather in subchromosomal changes or even in epigenetics than in gross structural alterations.
