Cytogenetic studies showed that this species has 2n=50 chromosomes, 18 metacentrics, 18 submetacentrics, 10 subtelocentrics and 4 acrocentrics. The Ag-NORs are restricted to a single large metacentric pair in the interstitial position on the long arm. © 2006 The Japan Mendel Society.257-259engAg-NORsChromosome evolutionFish cytogeneticsKaryotypesScoloplacidaeScoloplaxSiluriformesTeleosteiArtigo10.1508/cytologia.71.257Acesso aberto2-s2.0-337507264292-s2.0-33750726429.pdf0804793944846367
