Figure 3. Evidence for BDMIs being the major source of selection on hybrids.

Figure 3

(A, B) Correlations in ancestry between independently formed swordtail hybrid populations (in 0.1 cM windows; Fig. S9). Points show the mean and whiskers indicate two standard errors of the mean; correlations are calculated on unbinned data. (C) Predictions for different sources of selection on hybrids. (D) Average minor parent ancestry is unusually depleted in 50 kb windows containing putative unlinked BDMIs (red points, from 23) compared to 1,000 null datasets (blue; see 21). Importantly, low minor parent ancestry at putative BDMIs is not expected as a result of how they were originally identified (21).
