The karyotypes of Cebus capucinus and C. nigrivittatus (Primates, Platyrrhini) are compared after applying several banding techniques. The chromosomes have abundant intercallary heterochromatin which can be stained by R-, T- and C-band techniques and which are late replicating. The X chromosome resembles that of man and of numerous primates. However, the late replicating pattern of the X in female lymphocytes resembles that of the late replicating X of human fibroblasts rather than of human… Expand
Constitutive heterochromatin polymorphism in Lagothrix lagothricha cana, Cebus apella, and Cebus capucinus
TLDR
The C‐banding patterns show both a high degree of polymorphism as well as the presence of terminal and interstitial C‐bands in the karyotypes of Lagothrix lagothricha cana, Cebus apella and Cebus capucinus. Expand
Sequence of late DNA replication in Cebus capucinus chromosomes and a standardized G‐banded karyotype
TLDR
A standardized G‐banded idiogram for Cebus capucinus was proposed and the complete late replication sequence for about 200 bands was established and many chromosomes thought to be homologous on the basis of R‐banding and gene mapping showed similar replication sequences to human and macaque chromosomes.

Heterochromatin and chromosome evolution: a FISH probe of Cebus apella paraguayanus (Primate: Platyrrhini) developed by chromosome microdissection.
TLDR
It is proposed that the heterochromatin observed in CAPp and CAPn is specific for these species, and is considered as a possible key for the interpretation of chromosomal evolution in these Ceboidea. Expand
The Karyotype and C-Banding of Cebus nigrivittatus from the Coastal Cordillera, Venezuela
TLDR
A first step towards its karyosystematics is taken by characterizing its most abundant subspecies, C. nigrivittatus brunneus, as a preliminary report on the chromosomal differentiation of the species and as a contribution to the systematic study of the genus. Expand
Chromosomal evolution in Primates: Tentative phylogeny from Microcebus murinus (Prosimian) to man
TLDR
The karyotypes of more than 60 species of Primates are studied and compared, with the use of almost all existing banding techniques, and a fairly precise genealogy of many Primates is proposed, giving the positions of the Catarrhines, the Platyrrhines, and the Prosimians is proposed. Expand
Detection of G-C rich heterochromatin by 5-azacytidine in mammals
TLDR
5-ACR treatment can be used as a simple method for the detection of G-C rich heterochromatin in primates and in fibroblast or kidney cell cultures. Expand
Genome Size of Two Cebus Species (Primates: Platyrrhini) with a Fertile Hybrid and Their Quantitative Genomic Differences
TLDR
Findings on C-value quantification support the species status for C. libidinosus and C. nigritus, as the hybrid genome contains a greater amount of DNA in the heterochromatic blocks related to those in the genomes of both parental species. Expand
What do we know about the heterochromatin of capuchin monkeys (Cebus: Platyrrhini)?
TLDR
This document analizes las investigaciones cientificas y Tecnicas y naturales de Buenos Aires registrada por el Consejo Nacional de Investigaciones Cientific as well as las oficina de Coordinacion Administrativa Ciudad Universitaria y el departamento de Ecologia, Genetica y Evolucion. Expand
Bibliography of cytogenetic studies of platyrrhini
TLDR
A bibliographic review of karyological studies on New World monkeys which is current to July 1983 is presented, which includes the diploid number and the chromosomal banding techniques utilized. Expand
Primates karyological diagnosis and management programs applications
Captive primates are often maintained in groups without geographic origin or genetic heritage information. This could lead to an incorrect assignment of species, which could result in an inadequateExpand
