Despite decades of cytogenetic and genomic research of dynamic sex chromosome
evolution in teleost fishes, multiple sex chromosomes have been largely neglected. In this …

The impact of sex chromosomes and their turnover in speciation remains a subject of
ongoing debate in the field of evolutionary biology. Fishes are the largest group of …

Rineloricaria is the most diverse genus within the freshwater fish subfamily Loricariinae, and
it is widely distributed in the Neotropical region. Despite limited cytogenetic data, records …

Harttia comprises an armored catfish genus endemic to the Neotropical region, including 27
valid species with low dispersion rates that are restricted to small distribution areas …

The Neotropical monophyletic catfish genus Harttia represents an excellent model to study
karyotype and sex chromosome evolution in teleosts. Its species split into three phylogenetic …

The Neotropical armored catfish genus Harttia presents a wide variation of chromosomal
rearrangements among its representatives. Studies indicate that translocation and …

Sex chromosome differentiation is subject to independent evolutionary processes among
different lineages. The accumulation of repetitive DNAs and consequent crossing-over …

The scattered distribution pattern of microsatellites is a challenging problem in fish
cytogenetics. This type of array hinders the identification of useful patterns and the …

The Neotropical genus Harttia comprises species with extensive chromosomal remodeling
and distinct sex chromosome systems (SCSs). So far, three different SCSs with male …

The Erythrinidae family (Teleostei: Characiformes) is a small Neotropical fish group with a
wide distribution throughout South America, where Hoplias malabaricus corresponds to the …
