Chromosome painting of Z and W sex chromosomes in Characidium (Characiformes, Crenuchidae)
(2013-01-24)
Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important ...

Chromosomal Mapping of Repetitive DNAs in Characidium (Teleostei, Characiformes): Genomic Organization and Diversification of ZW Sex Chromosomes
(Karger, 2015-01-01)
The speciose neotropical genus Characidium has proven to be a good model for cytogenetic exploration. Representatives of this genus often have a conserved diploid chromosome number; some species exhibit a highly differentiated ...
Differentiation and Evolution of the W Chromosome in the Fish Species of Megaleporinus (Characiformes, Anostomidae)
(2018-06-08)
The W chromosome of Megaleporinus trifasciatus was isolated in order to analyze its behavior in the karyotype of this and other species of the family, including forms with differentiated and undifferentiated sex chromosomes. ...
Chromosomal painting and ZW sex chromosomes differentiation in Characidium (Characiformes, Crenuchidae)
(Biomed Central Ltd., 2011-07-25)
Background: The Characidium (a Neotropical fish group) have a conserved diploid number (2n = 50), but show remarkable differences among species and populations in relation to sex chromosome systems and location of nucleolus ...

Sex chromosome composition revealed in Characidium fishes (Characiformes: Crenuchidae) by molecular cytogenetic methods
(De Gruyter Open Ltd, 2014-10-01)
The W chromosome of the fishes Characidium cf. fasciatum, Characidium sp. and Characidium cf. gomesi is heterochromatic, as is usually seen in most Characidium species. Samples of W-chromatin were collected by mechanical ...
Comparative analysis of sex chromosomes in Leporinus species (Teleostei, Characiformes) using chromosome painting
(2013-07-03)
Background: The Leporinus genus, belonging to the Anostomidae family, is an interesting model for studies of sex chromosome evolution in fish, particularly because of the presence of heteromorphic sex chromosomes only in ...
