Gene mapping in the spider monkey (Ateles paniscus chamek)

Sixteen isozyme markers have been assigned to the chromosome complement of the neotropical primate species Ateles paniscus chamek using three somatic cell hybrid panels. Several genetic associations were found to be common between humans and this species, despite the fact that Ateles is a karyologically rearranged taxon. Conversely, several human gene clusters were disrupted, resulting in gene associations not previously found in other primates. A comparison with other primates and mammalian orders, for which gene maps are available, was carried out for a comprehensive evaluation of genome evolution in these disparate taxa.
