The Teleostei represent approximately 96% of all living fishes and comprise 23.637 species,
grouped in 426 families and 38 orders (Nelson, 1994). The cytotaxonomic knowledge of this …

The diploid–polyploid Squalius alburnoides complex resulted from interspecific
hybridization. The chromosomal mapping of 28S and 5S ribosomal genes and of (TTAGGG) …

The chromosomes of the diploid and tetraploid loach Misgurnus anguillicaudatus were
