The concentration of evolutionary breakpoints in primate karyotypes in some particular
regions or chromosome bands suggests that these chromosome regions are more prone to …

In this study we evaluated the performance of the cytochrome c oxidase subunit II (COII)
mitochondrial gene as a tool for inferring phylogenetic relationships among platyrrhines …

ZOO‐FISH (Fluorescent “in vitro” hybridization) was used to establish the chromosomal
homology between humans (HSA) and Cebus nigrivitatus (CNI) and Ateles belzebuth …

Background Chromosomal painting, using whole chromosome probes from humans and
Saguinus oedipus, was used to establish karyotypic divergence among species of the genus …

Most primates studied have the usual XX/XY sex‐chromosome system. However, exceptions
to this rule among howler monkeys have been suggested by several authors. Recently a …

With just five species, the Paraguayan primate fauna is less diverse than its neighbours and,
perhaps as a result of this, few biologists have chosen the country for their primate studies …

Homologous chromosomes exchange genetic information through recombination during
meiotic synapsis, a process that increases genetic diversity and is fundamental to sexual …

We have analysed the expression of aphidicolin-induced common fragile sites at two
different aphidicolin concentrations (0.1 mmol/L and 0.2 mmol/L) in three female and one …

Neotropical Primate karyotypes are highly variable, particularly in the heterochromatic
regions, not only regarding the amount of heterochromatin, but also the composition. G and …

Arnaldo de Winkelried Bertoni (1878–1973) was the principal student of the Paraguayan
fauna during the early 20th Century. The publication widely considered to be his “magnum …
