[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE] Whereas inferred IBD sharing does not indicate directionality, the North African samples that have highest IBD sharing with Iberian populations also tend to have the lowest proportion of the European cluster in ADMIXTURE (Fig. 1), e.g., Saharawi, Tunisian Berbers, and South Moroccans. For example, the Andalucians share many IBD segments with the Tunisians (Fig. 3), who present extremely minimal levels of European ancestry. [b]This suggests that gene flow occurred from Africa to Europe rather than the other way around.[/b] [...] Alternative models of gene flow: Migration(s) from the Near East likely have had an effect on genetic diversity between southern and northern Europe (discussed below), but do not appear to explain the gradients of African ancestry in Europe. A model of gene flow from the Near East into both Europe and North Africa, such as a strong demic wave during the Neolithic, could result in shared haplotypes between Europe and North Africa. [b]However, we observe haplotype sharing between Europe and the Near East follows a southeast to southwest gradient, while sharing between Europe and the Maghreb follows the opposite pattern (Fig. 2); this suggests that gene flow from the Near East cannot account for the sharing with North Africa.[/b][/QUOTE]--Laura R.
