Resumo: | This study described the karyotype of Geophagus cf. proximus. Specimens were collected in Água Preta Lake, Parque Ambiental de Belém, Pará State, Brazil. The karyotype were 2n = 48 chromosomes (FN = 60: 12M/SM+36ST/A) and no sexual chromosome differentiation. C-banding showed centromeric staining in all chromosomes. The first chromosome pair, besides centromeric coloration, presented a totally heterochromatic long arm. The nucleolus organizer regions (NORs) were studied by means of AgNO3. NORs were located at the short arm of the second chromosome pair. |
