Goes, Caio Augusto Gomes [UNESP]; Silva, Duílio Mazzoni Zerbinato De Andrade [UNESP]; Utsunomia, Ricardo; Nascimento, Nivaldo Ferreira DoMade available in DSpace on 2022-04-29T08:38:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-12-01; B chromosomes are additional dispensable elements to the standard chromosomal set of an organism. In most cases, their transmission differs from Mendelian patterns, leading to their accumulation or extinction. The present study aimed to describe, for the first time, the transmission pattern of B chromos...

Voltolin, Tatiana Aparecida [UNESP]; Senhorini, José Augusto; Oliveira, Cláudio [UNESP]; Foresti, Fausto [UNESP]; Bortolozzi, Jehud [UNESP]Made available in DSpace on 2022-04-28T21:02:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-01-01; Prochilodus lineatus is widely used in pisciculture projects, mainly in the south of Brazil. It shows a basic karyotype composed of 2n = 54 chromosomes, in addition to as many as seven supernumerary chromosomes, also known as B-chromosomes. These additional small chromosomes are frequently heterochromat...

No. of bitstreams: 0 Previous issue date: 2021-01-01; This study reports the first cytogenetic characterization of the Amazonian catfish Leiarius marmoratus (“jandiá”) and its F1 (first generation) hybrid “cachandiá” with Pseudoplatystoma reticulatum (“cachara”). A diploid number of 56 chromosomes and a single argyrophilic nucleolus organizer region (Ag-NO...

No. of bitstreams: 0 Previous issue date: 2021-09-01; B chromosomes occur in different species of the small characid fishes of the genus Moenkhausia. These supernumerary elements, that do not recombine with chromosomes of the standard A complement and follow their own evolutionary mechanism vary in number, morphology, and distribution. Here, we show karyot...

Freitas-Souza, Diogo [UNESP]; Nobile, André Batista [UNESP]; do Prado, Fernanda Dotti [UNESP]; Serrano, Érica Alves [UNESP]Made available in DSpace on 2022-05-01T12:40:49Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Due to the constant propagule pressure of invasive species, aquaculture is considered to be one of the principal mechanisms for the introduction of non-native fish species into wild habitats in Brazil. The ongoing expansion of fish farming in many inland areas is linked directly to the increase in the p...
