Model of ancestry-enabled selection at the MHC locus in the Colombia population. a Modeled levels of ancestry enrichment and depletion (zanc, y-axis) corresponding to a range of different selection coefficients (s, x-axis): African (blue), European (orange), and Native American (red). The intersection of the observed level of African ancestry enrichment at the MHC locus and the corresponding s value is indicated with dashed lines. b The trajectory of predicted ancestry enrichment and depletion (zanc,y-axis) over time (t generations, x-axis) is shown for the inferred selection coefficient of s = 0.05.
