Extensive nucleolus organizer region polymorphism in Gymnotus carapo (Gymnotoidei, Gymnotidae).

Cytogenetics and cell genetics - 1 Jan 1997

Fernandes-Matioli F M, Almeida-Toledo L F, Toledo-Filho S A

Abstract excerpt

An investigation was conducted on six populations of Gymnotus carapo from the Upper Parana river system in Brazil. A wide variability of the NOR-bearing chromosomes was found involving paracentric inversions in the heterochromatic regions associated with NORs, resulting in 5 NOR chromosome phenot...
