Chromosomal homologies between Cebus and Ateles (Primates) based on ZOO‐Fish and G‐banding comparisons
ZOO‐FISH (Fluorescent “in vitro” hybridization) was used to establish the chromosomal homology between humans (HSA) and Cebus nigrivitatus (CNI) and Ateles belzebuth hybridus (ABH). These two species belong to different New World monkey families (Cebidae and Atelidae, respectively) which differ greatly in chromosome number and in chromosome morphology. The molecular results were followed by a detailed banding analysis. The ancestral karyotype of …
Characterization of constitutive heterochromatin inCebus apella(Cebidae, Primates) andPan troglodytes (Hominidae, Primates): Comparison to human chromosomes
Using G bands, some homologies between the chromosomes of Cebus apella (CAP) and human chromosomes are difficult to establish. To solve this problem, we analyzed these homologies by fluorescence in situ hybridization using human whole chromosome probes (ZOO-FISH). The results indicated that 1) the human probe for chromosome 2 partially hybridizes with CAP chromosomes 13 and 5, 2) the human probe for chromosome 3 partially hybridizes with CAP chro…
Radiation and speciation of spider monkeys, genus Ateles, from the cytogenetic viewpoint
The chromosomes of 22 animals of four subspecies of the genus Ateles (A. paniscus paniscus, A. p. chamek, A. belzebuth hybridus, and A. b. marginatus) were compared using G/C banding and NOR (nucleolar organizer region) staining methods. The cytogenetic data of Ateles in the literature were also used to clarify the phylogenetic relationships of the species and subspecies and to infer the routes of radiation and speciation of these taxa. Chromosom…

Heterochromatin and cytogenetic polymorphisms in Cebus apella (Cebidae, Platyrrhini)
Cytogenetic studies have been carried out in 39 specimens of C. apella of different origins. Three different morphologies, one affecting the long arm of chromosome 4 and two affecting pair 17, have been detected. In each case, they can be related by paracentric inversions. Heterochromatin polymorphisms affecting terminal or interstitial C+ regions have also been observed. The length of the terminal heterochromatic region in the long arms of chrom…
Prometaphase chromosomes of the howler monkey ( Aloutta caraya ): G, C, NOR, and restriction enzyme (RE S ) banding
Prometaphase lymphocyte chromosomes from eight adult argentinian Alouatta caraya females were characterized using sequential G‐C banding techniques, Ag‐NOR bands and bands obtained with the restriction enzymes Hae III, Eco RI, Alu I and Sau 3A. The cytogenetic analysis showed 2n = 52, with four, five, or six NOR chromosomes. Digestion with Hae III and Eco RI produced G‐like‐bands. Centromere regions and two interstitial C‐bands (in chromosomes nu…

High‐resolution chromosome banding studies in Cebus apella , Cebus albifrons , and Lagothrix lagothricha: Comparison with the human karyotype
Karyotypes of three species of South American primates ( Cebus apella, Cebus albifrons , and Lagothrix lagothricha ) were studied using high‐resolution banding techniques, and were compared to the human karyotype. The number of homologies was very high for the three species. Some of the breakpoints implicated in chromosome rearrangements corresponded with human fragile sites. The fragile sites in human chromosomes often correspond with the locali…
Comparative chromosome banding studies in the family Cercopithecidae
Constitutive heterochromatin polymorphism in Lagothrix lagothricha cana, Cebus apella , and Cebus capucinus
We describe the C‐bands in the karyotypes of Lagothrix lagothricha cana, Cebus apella and Cebus capucinus. The C‐banding patterns show both a high degree of polymorphism as well as the presence of terminal and interstitial C‐bands. Varying amounts of heterochromatin result in dimorphism of some chromosome pairs. The high incidence of chromosome rearrangements found in the Cebidae may be due to the presence of terminal and interstitial C‐bands

Q and G banding patterns of the chromosomes of some Primates
Chromosome variability in the Lemuridae
Chromosome studies have been conducted in Lemur catta, L. macaco, L. mongoz, L. fulvus fulvus , and a hybrid L. fulvus fulvus x L. fulvus albifrons . Comparative analysis shows that inter‐ and intraspecific chromosome variability is a common finding in Lemurs. The Lemuridae are divided into three groups according to the characteristics of their chromosome complement. A reclassification of L. catta with the Hapalemurs is suggested, based on chromo…
