The karyotypes of two taxa of genus Leontopithecus (rosalia and chrysomelas) are studied. Their G-, C- and NOR-banding patterns are compared with those of representatives of the genus Saguinus to determine chromosomal similarities and differences between the two genera and thus contribute to explaining phylogenetic relations between the tamarins ...

Biochemical Genetics, 1998
Five hundred forty-three blood samples from 15 populations of the four genera of callitrichin primates were studied electrophoretically. Polymorphism and genetic distances were estimated for 20 loci, 13 of which were polymorphic. The lion tamarin (Leontopithecus) studied here exhibited the least variability for these loci, while the monospecific ...

Comparative karyology and evolution of the Amazonian Callithrix (Platyrrhini, Primates)
Chromosoma, 1996Chromosomal studies in three species of Amazonian Callithrix (2n=44) and data in the literature show that this group is karyomonotypic. Moreover, it is characterized by the presence of abundant heterochromatic regions, unlike the situation in congeneric forms of Callithrix of the Atlantic coast with 2n=46, and by the presence of a highly repetitive ...

The meiotic chromosomes of Cebus apella (Cebidae, Platyrrhini).
Cytogenetics and cell genetics, 1984An analysis of the meiotic chromosomes of Cebus apella (Cebidae, Platyrrhini) has allowed for the visualization of constitutive heterochromatic regions throughout the meiotic cycle and has permitted the identification of four chromosomes in the first and the second divisions.

Satellite DNA sequences in the neotropical marmoset Callimico goeldii (Primates, Platyrrhini)
Chromosoma, 1989Two families of tandemly repeated satellite DNAs were isolated from the neotropical primate Callimico goeldii (Goeldi's marmoset). One satellite, CgoA, is over 70% A + T and has a monomer length of 338 bp. The other satellite, CgoB, is 50% A + T and has a monomer length of 916 bp.

A fully resolved genus level phylogeny of neotropical primates (Platyrrhini)
Molecular Phylogenetics and Evolution, 2009There are more than 125 species of extant New World monkeys (Primates: Platyrrhini) found in approximately 15 genera. The phylogenetic relationships of these neotropical primates have been extensively studied from a molecular perspective. While these studies have been successful at inferring many of the relationships within the platyrrhines, key ...

Primates, 1999
Two cytochromeb pseudogenes were isolated from PCR amplified products ofCebuella pygmaea DNA. These sequences showed insertions and deletions when compared to paralogous mitochondrial sequence regions of several primates. Phylogenetic analyses indicated that an ancestral pseudogene originated sometime before the divergence ofCebuella andCallithrix and ...

Comparative chromosomal study of five taxa of genusCallithrix, groupJacchus (Platyrrhini, primates)
American Journal of Primatology, 1997The karyotypes of four marmoset species of the Callithrix jacchus group (C. aurita, C. kuhlii, C. geoffroyi, and C. penicillata) were investigated. The patterns of G-, C-, and NOR-bands of these karyotypes were compared with those of C. jacchus, previously described, in order to clarify the taxonomic relationships of this species group.
