Figure 3. Model of selection, deme size (N) , migration rate
(m), and generations in admixture modify the distribution ofFST values, FPR, and FNR in different
degrees. Mode of selection modifies only FST and
FNR, with strong genomic differentiation even
without any need for selection. Underdominant selection and BDM
incompatibilities increased FNR. Deme size influencedFST , FPR, and FNR. Small deme sizes
showed higher rates of differentiation and large deme sizes produce
significantly less false positives and false negatives. Migration
rate influenced only FST and FPR, with low
migration rates increasing genomic differentiation and generating more
false positives. Old hybrid zones increasedFST values, FPR, and FNR, and
specifically generate more false positives and false negatives. N.S. -
