(a)–(f) Spatial frequency maps of haplogroup G (hg G) and its sub-clades with frequencies over 10%. In the case of the general frequency pattern of hg G, panel (a) was obtained by applying the frequencies from Supplementary Table S1 together with data taken from the literature, concerning 569 individuals representing 7 populations comprising Algerians,⁴⁷ Oromo and Amhara Ethiopians,⁴⁸ and Berbers, Arabs and Saharawis from Morocco.⁴⁹ Dots on the map (a) indicate the approximate locations of the sampled populations. Spatial frequency maps for sub-clades (panels b–f) were obtained by applying the frequencies from Supplementary Table S1 using the Surfer software (version 8, Golden Software, Inc.), following the kriging algorithm with option to use bodies of water as breaklines.
