Kretschmer, Rafael; Goes, Caio Augusto Gomes [UNESP]; Bertollo, Luiz Antônio Carlos; Ezaz, Tariq; Porto-Foresti, Fábio [UNESP]; Toma, Gustavo AkiraMade available in DSpace on 2022-05-01T13:41:26Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Satellites are an abundant source of repetitive DNAs that play an essential role in the chromosomal organization and are tightly linked with the evolution of sex chromosomes. Among fishes, Triportheidae stands out as the only family where almost all species have a homeologous ZZ/ZW sex chromosomes syste...

An Insight into the Chromosomal Evolution of Lebiasinidae (Teleostei, Characifo...
Sassi, Francisco de Menezes Cavalcante; Hatanaka, Terumi; Moraes, Renata Luiza Rde; Toma, Gustavo Akira; Oliveira, Ezequiel Aguiar de; Liehr, ThomasLebiasinidae fishes have been historically neglected by cytogenetical studies. Here we present a genomic comparison in eleven Lebiasinidae species, in addition to a review of the ribosomal DNA sequences distribution in this family. With that, we develop ten sets of experiments in order to hybridize the genomic DNA of representative species from the genus Copeina, Copella, Nannostomus, and Pyrrhulina in metaphas...
Cytogenetics of the small-sized fish, Copeina guttata (Characiformes, Lebiasini...
Toma, Gustavo Akira; Moraes, Renata Luiza Rosa de; Sassi, Francisco de Menezes Cavalcante; Bertollo, Luiz Antônio Carlos; Oliveira, Ezequiel Aguiar deLebiasinidae is a small fish family composed by miniature to small-sized fishes with few cytogenetic data (most of them limited to descriptions of diploid chromosome numbers), thus preventing any evolutionary comparative studies at the chromosomal level. In the present study, we are providing, the first cytogenetic data for the red spotted tetra, Copeina guttata, including the standard karyotype, C-banding, rep...
