Chromosomal diversification in populations of Characidium cf. gomesi (Teleostei, Crenuchidae)
(Wiley-Blackwell Publishing, Inc, 2011-01-01)
Comparative cytogenetic studies carried out in two populations of Characidium cf. gomesi from Botucatu region, SP, Brazil, showed a similar karyotypic structure in a diploid number of 50 chromosomes, 32 metacentric and 18 ...

DNA transposon invasion and microsatellite accumulation guide W chromosome differentiation in a Neotropical fish genome
(Springer, 2019-12-01)
Sex chromosome differentiation is subject to independent evolutionary processes among different lineages. The accumulation of repetitive DNAs and consequent crossing-over restriction guide the origin of the heteromorphic ...
Single Origin of Sex Chromosomes and Multiple Origins of B Chromosomes in Fish Genus Characidium
(Public Library Science, 2014-09-16)
Chromosome painting with DNA probes obtained from supernumerary (B) and sex chromosomes in three species of fish genus Characidium (C. gomesi, C. pterostictum and C. oiticicai) showed a close resemblance in repetitive DNA ...
Chromosome mapping of repetitive sequences in Anostomidae species: Implications for genomic and sex chromosome evolution
(2012-12-01)
Background: Members of the Anostomidae family provide an interesting model system for the study of the influence of repetitive elements on genome composition, mainly because they possess numerous heterochromatic segments ...

Patterns of Z chromosome divergence among Heliconius species highlight the importance of historical demography
(2018)
Sex chromosomes are disproportionately involved in reproductive isolation and adaptation. In support of such a “large-X” effect, genome scans between recently diverged populations and species pairs often identify distinct ...
