DescriptionMap of African admixture in European populations.png
English: Map illustrating the extent and pattern of recent gene flow between European and African populations using SNP data from seven North African populations, together with data from 30 European populations, two European Jewish populations, one Near Eastern population (29), and HapMap3 Sub-Saharan African populations. Allele frequencies are used to estimate North African ancestry proportions in European populations. To quantify the variance in ancestry in European populations and obtain bounds on the time since admixture, a quantitative model is used for the decrease in ancestry variance with the time since admixture. Gene flow between populations is also detected by analyzing long haplotypes shared identically by descent (IBD) with high-density SNP genotyping data. A significant latitudinal gradient of North African ancestry within Europe characterized by a dramatic difference between the Iberian Peninsula and the neighboring regions.
