Diagram of origin of terminal rDNA clusters in metacentric chromosome from Sericomyrmex maravalhas, considering its ancestor with intrachromosomal rDNA clusters. Black bars: chromosomal breaks; Fis: centric fission; Inv: pericentric inversion; Green blocks: GC-rich regions; Red blocks: 18S ribosomal clusters.
