Abstract
The karyotype of the neotropical primate genus Cebus (Platyrrhini: Cebidae), considered the most ancestral one, shows the greatest amount of heterochromatin described among Platyrrhini genera. Banding techniques and restriction enzyme digestion have previously revealed great variability of quantity and composition of heterochromatin in this genus. In this context, we use fluorescence in situ hybridization (FISH) to analyse this genomic region and discuss its possible role in the diversification of Cebus.We used a heterochromatin probe for chromosome 11 of Cebus libidinosus (11qHe+ CLI probe), obtained by chromosome microdissection. Twenty-six specimens belonging to the families Atelidae, Cebidae, Callitrichidae and Pithecidae (Platyrrhini) were studied. Fourteen out of 26 specimens were Cebus (Cebidae) individuals of C. libidinosus, C. xanthosternos, C. apella, C. nigritus, C. albifrons, C. kaapori and C. olivaceus. In Cebus specimens, we found 6 to 22 positive signals located in interstitial and telomeric positions along the different species. No hybridization signal was observed among the remaining Ceboidea species, thus reinforcing the idea of a Cebus-specific heterochromatin composed of a complex system of repetitive sequences.

Abstract
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) against two proteins of the Synaptonemal Complex (SC), namely REC8 and SYCP1, two recombination protein markers (RPA and MLH1), and one protein involved in the pachytene checkpoint machinery (BRCA1) was performed in CPA spermatocytes in order to analyze chromosome meiotic behavior in detail. RESULTS Although in the vast majority of pachytene cells all autosomes were paired and synapsed, in a small number of nuclei the heterochromatic C-positive terminal region of bivalent 11 remained unpaired. The analysis of 75 CPA cells at pachytene revealed a mean of 43.22 MLH1 foci per nucleus and 1.07 MLH1 foci in each CPA bivalent 11, always positioned in the region homologous to HSA chromosome 21. CONCLUSION Our results suggest that C blocks undergo delayed pairing and synapsis, although they do not interfere with the general progress of pairing and synapsis.

Abstract
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 chromosomes 18 and 20, 3) the human probe for chromosome 9 partially hybridizes with CAP chromosome 19, and 4) the human probe for chromosome 14 hybridizes with the p-terminal and q-terminal regions of CAP chromosome 6. However, none of the human probes employed hybridized with the heterochromatic regions of CAP chromosomes. For this reason, we characterized the heterochromatic regions of CAP chromosomes and of the chromosomes of Pan troglodytes (PTR), to allow comparison between CAP, PTR, and human chromosomes using in situ digestion of fixed chromosomes with the restriction enzymes AluI, HaeIII, and RsaI and by fluorescent staining with DA/DAPI. The results show that 1) centromeric heterochromatin is heterogeneous in the three species studied and 2) noncentromeric heterochromatin is homogeneous within each of the three species, but is different for each species. Thus, centromeric heterochromatin undergoes a higher degree of variability than noncentromeric heterochromatin.

Abstract
In this paper, we describe the results of a qualitative and quantitative study of chromosomal reorganizations observed in X-irradiated (1Gy and 2Gy) and cultured lymphocytes from Cebus apella. A total of 646 breakpoints have been detected, identified and localized in the ideogram of the species. The breakpoint distribution along chromosomes, p and q arms, and bands is not random. Chromosomes #11, #12 and chromosome arms 1p, 12p, 13p, 15p, 11q, and 12q are significantly more affected than expected, while chromosome #19 and chromosome arm 19q are less affected. Terminal regions of chromosome arms accumulate a higher number of breakpoints than the rest of the chromosome (37.82%). A high percentage (93.66%) of breakpoints is found in G negative bands.

Abstract
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 chromosome 11 is variable in C. apella sp., in C. a. paraguayanus and absent in the C. a. nigritus specimens studied. Interstitial C + bands can be observed in the long arms of the biarmed chromosomes 4 and 6, and in the long arms of the acrocentric pairs 12, 13, 17, 18, 19, 20, and 21. Interstitial C + bands in the long arms of chromosomes 4, 12, 17, and 19 are present in all animals studied, although their size is variable, especially in the case of chromosomes 17 and 19. © 1995 Wiley-Liss, Inc.

Abstract
The karyotype of Ateles geoffroyi (Cebidae; Primates; Mammalia) was studied using G- and C-banding techniques, and standardized idiograms are proposed. A polymorphism of chromosome 3 due to a pericentric inversion has been identified for the first time. Genetic analysis of this polymorphism showed Mendelian inheritance.
