Resumo: | The chromosomal localization of the As51 satellite DNA was identified by fluorescent in situ hybridization (FISH) in specimens of the characid fish Astyanax scabripinnis and Astyanax fasciatus, which are considered species complexes because of their extensive karyotypical and morphological variability. A conserved chromosomal distribution of the As51 satellite, coincident with distal C-banded segments was demonstrated. The alternative interstitial localization of this satellite DNA and possible alterations of its structure suggest that this sequence underwent quantitative, positional and structural variations, as the A. scabripinnis and A. fasciatus complexes diverged.
