Multiple sex chromosome systems in howler monkeys (Platyrrhini, Alouatta) [PDF]
Comparative Cytogenetics, 2014 In light of the multiple sex chromosome systems observed in howler monkeys (Alouatta Lacépède, 1799) a combined cladistic analysis using chromosomal and molecular characters was applied to discuss the possible origin of these systems ...

Molecular phylogeny of the genus Saguinus (Platyrrhini, Primates) based on the ND1 mitochondrial gene and implications for conservation [PDF]
Genetics and Molecular Biology, 2005 The systematics of the subfamily Callitrichinae (Platyrrhini, Primates), a group of small monkeys from South America and Panama, remains an area of considerable discussion despite many investigations, there being continuing controversy over subgeneric ...

Pairing and recombination features during meiosis in
BMC Genetics, 2009 Background Among neotropical Primates, the Cai monkey Cebus paraguayanus (CPA) presents long, conserved chromosome syntenies with the human karyotype (HSA) as well as numerous C+ blocks in different chromosome pairs. In this study, immunofluorescence (IF)

Chromosome phylogeny of the subfamily Pitheciinae (Platyrrhini, Primates) by classic cytogenetics and chromosome painting [PDF]
BMC Evolutionary Biology, 2010 Background The New World monkey (Platyrrhini) subfamily Pitheciinae is represented by the genera Pithecia, Chiropotes and Cacajao. In this work we studied the karyotypes of Pithecia irrorata (2n = 48) and Cacajao calvus rubicundus (2n = 45 in males and ...

The prion protein and New World primate phylogeny [PDF]
Genetics and Molecular Biology, 2004 The PrP C prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrP C is converted to PrP Sc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Genetics and Molecular Biology, 2000 Traditional classifications of Platyrrhini monkeys, based mainly on morphological features, are being contested by recent molecular data. The subfamily Callitrichinae (Platyrrhini, Primates) consists of a diverse group of species, many of them considered

Endocranial shape variation and allometry in Euarchontoglires [PDF]
Scientific ReportsWhile brain size in primates and their relatives within Euarchontoglires is well-studied, less research has examined brain shape, or the allometric trajectories that underlie the relationship between size and shape.

WHAT DO NEOTROPICAL PRIMATES TELL US UNDER THE LOOK OF CYTOGENETICS? [PDF]
BAG. Journal of Basic and Applied Genetics, 2022 Cytogenetics studies in Neotropical Primates (Primates: Platyrrhini) have shown that these mammals comprise a heterogeneous group at the chromosomal level.

Patterns of MHC-G-Like and MHC-B Diversification in New World Monkeys. [PDF]
PLoS ONE, 2015 The MHC class I (MHC-I) region in New World monkeys (Platyrrhini) has remained relatively understudied. To evaluate the diversification patterns and transcription behavior of MHC-I in Platyrrhini, we first analyzed public genomic sequences from the MHC-G-
