“…The coincident distribution of ribosomal genes, as well as the presence of homeologous and phylogenetically related sets of sm-st chromosomes (3 pairs) and m chromosomes (6 pairs) reveal the conservatism of large syntenic chromosomal regions in these species. This condition has been reported in other marine Perciformes (Molina, 2007;Molina et al, 2013;Motta-Neto et al, 2011a), revealing that chromosomal rearrangements have probably taken place during cladogenesis of these groups and remained fixed ever since.…”

“…Low heterochromatic content and homogeneous repetitive sequences have been associated with slow dynamics of karyotype repatterning imparting adverse conditions for high levels of genomic reorganization in some Percomorpha groups [Molina, 2007;Motta-Neto et al, 2011a, b, 2012Molina et al, 2013]. A high degree of chromosome homeology is expected in scenarios of low or slow genomic evolution .…”

“…Similarities in karyotype structure have been considered as a less restrictive condition for natural hybridization in some fish groups [Molina et al, 2013]. Genetic evidences suggest natural bidirectional hybridization between both C. undecimalis and C. parallelus [González, 2015], where the latter species is phylogenetically close to C. mexicanus [Tringali et al, 1999].…”

Centropomus is the sole genus of the Centropomidae family (Teleostei), comprising 12 species widely distributed throughout the Western Atlantic and Eastern Pacific, with 6 of them occurring in the Western Atlantic in extensive sympatry. Their life history and phylogenetic relationships are well characterized; however, aspects of chromosomal evolution are still unknown. Here, cytogenetic analyses of 2 Centropomus species of great economic value (C. undecimalis and C. mexicanus) were performed using conventional (Giemsa, Ag-NOR, and fluorochrome staining, C- and replication banding) and molecular (chromosomal mapping of 18S and 5S rDNA, H2A-H2B and H3 hisDNA, and (TTAGGG)_n repeats) approaches. The karyotypes of both species were composed of 48 solely acrocentric chromosomes (2n = 48; FN = 48), but the single ribosomal site was located in varying positions in the long arms of the second largest chromosome pair. Replication bands were generally similar, although conspicuous differences were observed in some chromosome regions. In both species, the histone H3 genes were located on 3 apparently homeologous chromosome pairs, but the exact position of these clusters differed slightly. Interspecific hisDNA and rDNA site displacements can indicate the occurrence of multiple paracentric inversions during the evolutionary diversification of the Centropomus genomes. Although the karyotypes remained similar in both species, our data demonstrate an unsuspected microstructural reorganization between them, driven most likely by a series of paracentric inversions.

“…In addition to vicariant events, the ecological mechanisms of speciation that contributed to species richness in this family (Rocha and Molina 2008), combined with special stable features of its karyotype (Nirchio et al 2007) could be the major causes of karyotype stasis. However, conservative karyotypes seem to be involved in the reduction of post-zygotic reproductive isolation (Molina et al 2013) by the occurrence of natural and induced hybrids in the Centrarchidae and Carangidae families (Koppelman 1994, Murakami et al 2007.…”

Mechanisms of accumulation based on typical centromeric drive or of chromosomes carrying pericentric inversions are adjusted to the general karyotype differentiation in the principal Actinopterygii orders. Here, we show that meiotic drive in fish is also supported by preferential establishment of sex chromosome systems and B chromosomes in orders with predominantly bi-brachial chromosomes. The mosaic of trends acting at an infra-familiar level in fish could be explained as the interaction of the directional process of meiotic drive as background, modulated on a smaller scale by adaptive factors or specific karyotypic properties of each group, as proposed for the orthoselection model.
