Geographical distribution of baboon species (Papio spp.) and MAOALPR allele frequencies of different populations. The bar plots show the frequency of pap8, pap9, and pap10-alleles for all sampled populations, labeled with letters a-j (for sample locations see Additional file 1: Table S1). Populations of the same species can vary considerably. Generally, frequencies of pap8 decrease and pap9 increase from populations in the south to populations in the north-west and north-east. South Africa P. ursinus does not adhere to this pattern, and southern P. cynocephalus mainly carries pap10. The geographical distribution of Papio spp. is adapted from Zinner et al. [46]. Kinda baboons (P. kindae), which are often recognized as a subspecies of P. cynocephalus, were not included in this study
