Comparative chromosome banding studies in the family Cercopithecidae

Comparative banding studies in eight species of the family Cercopithecidae, subfamily Cercopithecinae allowed us to identify the chromosomes that have been conserved and those that have undergone structural changes. The results suggest that while the ancestral karyotype of the Cercopithecini was probably similar to that of Cercopithecus aethiops, the ancestral complement of the cercopithecinae was probably of the type now found in the Papionini. Thus, after their divergence, one of the groups maintained an extremely stable chromosomal complement (Papionini 2n=42) while the other underwent extreme chromosomal rearrangements (Cercopithecini 2n=48-72). © 1986 Editrice II Sedicesimo.
