Chromosomal painting and ZW sex chromosomes differentiation in Characidium (Characiformes, Crenuchidae)
(Biomed Central Ltd., 2014)
Population differentiation and speciation in the genus Characidium (Characiformes: Crenuchidae): effects of reproductive and chromosomal barriers
(Wiley-Blackwell, 2014-03-01)
Both time and low gene flow are the key factors by which different biological species arise. The divergence process among lineages and the development of pre- or postzygotic isolation occur when gene flow events are lacking. ...
Origin and differentiation of a sex chromosome system in Parodon hilarii (Pisces, Parodontidae). Satellite DNA, G- and C-banding
(Kluwer Academic Publ, 2003-10-01)
A satellite DNA sequence of Parodon hilarii ( named pPh2004) was isolated, cloned and sequenced. This satellite DNA is composed of 200 bp, 60% AT rich. In situ hybridization ( FISH) results revealed that the satellite DNA ...

Sex determination studies in two species of teleost fish, Oreochromis niloticus and Leporinus elongatus
(Acad Sinica Inst Zoology, 1996-10-01)
Genetic analyses of sex determination have identified sex chromosomes in many teleost fish species. However, there are several cases for which sex ratios do not fit perfectly with the expectations of heterogametic systems, ...
Evolution and conservation of Characidium sex chromosomes
(2017-10-01)
Fish species exhibit substantial variation in the degree of genetic differentiation between sex chromosome pairs, and therefore offer the opportunity to study the full range of sex chromosome evolution. We used restriction-site ...
Interspecific chromosomal divergences in the genus Characidium (Teleostei: Characiformes: Crenuchidae)
(Sociedade Brasileira de Ictiologia, 2010-03-01)
Os cariótipos de sete espécies de peixes do gênero Characidium, três estudadas pela primeira vez, foram caracterizados com o uso das técnicas citogenéticas convencionais (Giemsa, Ag-RONs e bandamento-C). Todas as espécies ...
Repetitive DNA sequences and evolution of ZZ/ZW sex chromosomes in characidium (teleostei: characiformes)
