Cytogenetic Analyses of Pseudopimelodus mangurus (Teleostei: Siluriformes: Pseudopimelodidae)

open access: yesCYTOLOGIA, 2004
The cytogenetic analyses showed that Pseudopimelodus mangurus has a diploid number of 2n=54 chromosomes (6M, 26SM, 12ST and 10A), single Ag-NORs on the short arm of a middle-sized ST pair, identified as pair 19, and a very small amount of C-band positive segments in two chromosome pairs. The Ag-NORs are C-band positive.
