dc.description.abstractB chromosomes are reported in three different Amazonian cichlid species. One to three supernumerary microchromosomes were detected in the peacock bass Cichla monoculus (4 out of 28 specimens) and Cichla sp. (4 out of 13 specimens), and pike cichlids Crenicichla reticulata (2 out of 5 specimens), with no similar standard chromosomal morphology. C-banding revealed that B chromosomes are totally heterochromatic. We suggest two scenarios for the origin of these B chromosomes either by chromosomal breakdowns due to mutagenic action of methyl mercury present in the aquatic environment or by interspecific origin due to hybridization events.
