Investigating local ancestry at the HLA in the Wollof. a local ancestry across 2160 Wollof haplotypes at the 30-35Mb region of chromosome 6. b results of the binomial ancestry deviation test shows a significant increase in Nilo-Saharan (purple) ancestry between 32.2 and 33Mb. c ancestry proportions from a local painting analysis in a single Anuak individual showing Western African (dark blue) ancestry. d UCSC genes across this region. e genome-wide distribution of unique Nilo-Saharan donors in the Wollof. f the proportion of unique donors when each of 7 non-self ancestries are copied across the 30-35Mb region of chromosome 6. g the number of times the most common haplotype is copied; the colour under the line represents the ancestry of the most copied individual.
