Abstract: Karyological changes, both in number and structure, are defined as the onset of the speciation processes and may promote the evolutionary dynamics of ribosomal RNA gene families, 5S and 45S rDNAs. Numerous 45S rDNA repeats are tandemly arranged in one or more loci in the genome called nucleolar-organizer regions (NORs). Knowledge about the number of rDNA loci, together with their chromosomal distribution and structure, provides clues about organismal and molecular evolution at various phylogenet
