“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 ...
BrdU replication patterns demonstrating chromosome homoeologies in two fish species, genus Eigenmannia
(1988-01-01)
The karyotypes of two fish species (genus Eigenmannia) from Brazilian rivers were studied with various chromosome banding techniques. BrdU incorporation appears to be the most powerful method for identifying chromosome ...

Mapping of the Retrotransposable Elements Rex1 and Rex3 in Chromosomes of Eigenmannia (Teleostei, Gymnotiformes, Sternopygidae)
(2015-12-01)
Transposable elements constitute a remarkable fraction of the eukaryote genome and show particular capacity to move and insert in specific regions of the genome. This study identified the retrotransposable elements Rex1 ...
