Chromosome evolution in fish: sex chromosome variability in Eigenmannia virescens (Gymnotiformes : Sternopygidae)
(Karger, 2002-01-01)
New data are presented on the sex chromosomes of the fish species Eigenmannia virescens (Gymnotiformes, Sternopygidae). A new finding, involving the occurrence of ZZ/ ZW sex chromosomes, is described in specimens sampled ...

XX : XY sex chromosome system with X heterochromatinization: an early stage of sex chromosome differentiation in the Neotropic electric eel Eigenmannia virescens
(Karger, 2001-01-01)
An early stage of sex chromosome differentiation is reported to occur in the electric eel Eigenmannia virescens (Pisces, Sternopygidae) from populations of two tributaries of the Parana river system (Brazil). Cytogenetic ...
“In vivo” Occurrence of Premature Chromosomes Condensation in Kidney Cells of Eigenmannia virescens (Pisces, Sternopygidae)
(1992-01-01)
The occurrence of premature chromosome condensation (PPC) was demonstrated in cytological preparations developed in two out of five specimens of a fish, Eigenmannia virescens, 2n=38, analysed after a period they were ...

Karyotype diversity and patterns of chromosomal evolution in Eigenmannia (Teleostei, Gymnotiformes, Sternopygidae)
(Pensoft Publ, 2014-01-01)
Conventional (Giemsa, C-banding, Ag - NORs) and molecular [5S rDNA, 18S rDNA, (TTAGGG)(n)] cytogenetic techniques were employed to study six species of the genus Eigenmannia Jordan & Evermann, 1896. They exhibited diploid ...
