Legend:
Hominoidea ancestral karyotype. The number+letter on the right indicate specific human BACs reported in the Supplemental Table ST5.
Synteny arrangement differences with respect to humans are only due to peri- /paracentric inversions (with the exception of the 2p-2q fusion). These breaks are indicated as clones facing each other (3M/3B on ANC3q, for instance). When a chromosome remained unchanged in humans, its human nomenclature is reported in italics.
