Gene assignment in Ateles paniscus chamek (Platyrrhini, Primates). Allocation of 18 markers of human syntenic groups 1, 2, 7, 14, 15, 17 and 22

Eighteen markers allocated to human syntenic groups 1, 2, 7, 14, 15, 17 and 22 were assigned to the chromosome complement of the neotropical primate A teles paniscus chamek. These new allocations and existing gene charts in th is species were compared with chromosome painting patterns produced by huma n chromosome probes in the congeneric species Ateles geoffroyi and with ava ilable data on the human genome and gene mapping. These comparisons showed congruent findings in Ateles and provided good evidence of how several huma n syntenic groups were evolutionarily rearranged.
