Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations
(A) Map shows the distribution of the Nilotic component in Northeast African populations (at K = 7). (B) Estimated non-African (using a European group) admixture using f4-ratios (see Methods). (C) Admixture dates (in generations) of Sudanese populations estimated using patterns of LD decay . Numbers in red indicate multiple admixture events of which the oldest is shown. Populations without admixture dates had no significant results in the analyses for an admixture event between a Sudanese or South Sudanese population and a non-African population. See S7 Table for putative admixture sources.
