The Evolution of Human Chromosome 7 Syntenies in Eutheria, with Special Attention to Primates
2004
Genetic and cytogenetic comparison in between man and non-human primates has largely contributed to the knowledge of the evolution of the Order Primates, and in particular of man. Recently, the "Chromosome painting" approach indicated a strong conservation of syntenies in Eutheria. At present, a more precise identification of breakpoints and evolutionary related rearrangements can be obtained by BAC and locus specific in situ hybridi- sation. In spite to this situation the evolutionary history of different human autosomes remains a dilemma; at the same time, high resolution banded chromosome analysis confirms to be a valuable tool for the preliminary detection of fine rearrangements. This r…
Chromosomal Dynamics in Cercopithecini Studied by Williams-Beuren probe mapping
2010
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 ha…
