dc.description.abstractThe mitotic chromosomes, nucleolus organizer regions (NORs), C-banding pattern and nuclear DNA content of Mastacembelus armatus were studied. The karyotype (2n = 48; 10m + 6sm + 4st + 28a) was characterized by the presence of one chromosome pair with NORs and a small quantity of heterochromatin. The DNA content observed in erythrocyte nuclei of M. armatus was 1.39 +/- 0.08 pg. Comparison of this karyotype with those of other Synbranchiformes revealed a strong similarity, suggesting that small chromosome rearrangements may have been maintained during its evolutionary history.en
