Fig 4. Power to detect the adaptive introgression allele.

Fig 4

Here we plot the detection probability for VolcanoFinder as a function of the number of false positive signals from the genomic background that produce a higher peak. Panel A shows introgression from a rare hybridization event. Panel B shows introgression with higher migration rates: m = 30/N for strong selection 2Ns = 1000 and m = 300/N for weak selection 2Ns = 100. Divergence of the donor is Td = 4.0 (green) or Td = 2.5 (blue) in units of 4N generations. Here, N = 10, 000 diploid individuals, mutation rate μ = 1.25 × 10−8 per site per generation, and recombination rate r = 5 × 10−7 per site per generation.
