caryologia-1149	Dotti do Prado, Fernanda ; Abrigato de Freitas Mourão, Andrea; Foresti, Fausto; Senhorini, José Augusto; Porto-Foresti, Fabio	First cytogenetic characterization of the Amazon Catfish Leiarius marmoratus (Gill, 1870) and its hybrid with Pseudoplatystoma reticulatum (Eigenmann & Eigenmann, 1889)	2021	7	.pdf	application/pdf	4214	263	55	L. mar- moratus shared cytogenetic characteristics commonly observed in Pimelodidae fishes as a diploid number of 56 chromosomes, a global pattern of heterochromatic bands distributed in terminal, peri and centromeric areas of the chromosomes, single Ag-NOR and 5S rDNA sites (Swarça et al. 2007, Nirchio et al. 2013; Swarça et al. 2017, Girardi et al. 2018). Variability in the kary- otype formula without changes on the diploid number is a common feature in the Pimelodidae family, also veri- fied for other Pseudoplatystoma species (Porto-Foresti et al. 2000; Nirchio et al. 2003) and among the Pimelodi- dae family (Swarça et al 2000), which can be explained by structural chromosomal rearrangements as pericen- tric inversions during their evolution and speciation events (Swarça et al. 2000; 2000) A polymorphism of Ag-NOR marks between the homologous chromosomes were detected for L. marmo- ratus and P. reticulatum in this study (Fig.	cache/caryologia-1149.pdf	txt/caryologia-1149.txt
