“…According to a fi ssioning model starting from this genome (2n = 48) chromosomal evolution processes should have brought to a wide karyotypic variability in guenons (2n = 48-72). This model has been repeatedly proposed or debated by several authors (STOCK and HSU 1973;CHIARELLI 1968;DUTRILLAUX et al 1979). Fission/inversion mechanisms hypothesis allowed the identifi cation of several grouping inside the tribe (DUTRIL-LAUX et al 1988) in accordance to taxonomy (i.e.…”

“…The species of the "aethiops" group have been assigned to a new genus, Chlorocebus (GROVES 2001). The tribe is characterized by a notable variation in diploid number (2N = 48-72) (CHIARELLI 1968), and a high frequency of chromosomal rearrangements and polymorphisms. (DUTRILLAUX et al 1979;PONSÀ et al 1980;1981;STANYON and SINEO 1983;SINEO et al 1986;SINEO 1990), often undetected by chromosome painting approach (STANYON et al 2005;MOULIN et al 2008).…”

Chromosomal evolution in the tribe Cercopithecini and in related taxa is highly debated. Uncertainty in reconstruction is mainly related to the great genetic variability and polymorphism of the taxa. Recent molecular and karyological efforts individuate a split between genetically conservative, arbitrarily defi ned, "terrestrial" guenons and vervets, and genetically variable and derived "arboreal" guenons. We performed the mapping of WS loci probe (7q11.23) in order to verify the chromosomal dynamics of the genomes of three tree-dwelling species of the tribe: C. neglectus, C. mitis mitis, C. albogularis labiatus. Data from literature for the "ground-dwelling" Chlorocebus aethiops sabaeus has been compared with our results. The distribution of the WS probe showed a high genomic dynamics in the different species, with three different pattern of rearrangements. Starting from the ancestral synteny 7 found in Pongo pygmaeus (PPY), the present mapping demonstrates different location of the hybridizations signals. A parsimonious interpretation lead to the hypothesis that a pericentric inversion transformed the PPY orthologous in C. neglectus. The C. mitis and the strictly related C. a. labiatus demonstrate more complex, and derivative, rearrangements. According to the position of the WS signal, and to banding pattern analysis, C. mitis and C. albogoularis, underwent to the pericentric inversion, followed by a paracentric inversion and a successive interstitial fi ssion that fragmented the synteny. Starting from the PPY like orthologous a single and independent event, a centric fi ssion, that did not affect the WS position, occurred in Ch. aethiops producing a Gorilla gorilla like chromosome. Our results confi rm the hypothesis that chromosomal dynamics in Cercopithecini proceed by fi ssions and inversions and indicate the usefulness of the locus specifi c mapping approach for the identifi cation of intrachromosome rearrangements.

“…Also, it can be noted that Chiarelli [1973] described 23 pairs of nonacrocentric chromosomes by Giemsa staining in C. mona mona. In C. aethiops (2 n = 60), Chiarelli [1968] described 19 pairs of non acrocentric autosomes and nine pairs of acrocentric chromosomes.…”

The G- and C-banded karyotypes of five species of Cercopithecus are reported. The chromosome numbers are: for C. ascanius katangae 2 n = 66 (XX); for C. petaurista petaurista 2 n = 66 (XY); for C. mona mona 2 n = 68 (XX); for C. pogonias grayi 2 n = 12 (XY) and for C. hamlyni 2 n = 64 (XY). We always found three types of chromosome: metacentric, sub-metacentric and acrocentric. The ‘marker chromosomes’ typical of the Cercopithecidae are of the last type. The karyotype of C. pogonias grayi shows a characteristic pair of acrocentric autosomes which is again found in the hybrid karyotypes.

“…Yet, their karyotypes show a considerable variation both in diploid numbers (from 2n = 48 to 2n = 72) and chromosome morphol ogy. Furthermore, several cases of intraspecific variability have been described [Chiarelli, 1968]. However, most of the data on this genus were obtained using only conventional staining techniques and their interpretation is difficult.…”
