Recall and precision of detecting minor population. We simulated 20 pairs of populations separated by D ∈ {100, 200, . . . , 2000} generations of drift on the whole genome of Illumina 550K loci. For each D we constructed test individuals that were derived over G ∈ {1, 2, . . . , 20} generations of admixture from 2G − 1 ancestors from one population and one ancestor from the other (minor) population. Conditioned on the existence of at least one haploblock derived from the minor population, we measure the ability of HAPAA to identify these loci.
