Figure 2. Additional Evidence for Gene Flow among Sympatric Species in Costa Rica.

Figure 2

(A–D) Sympatric H. melpomene and H. cydno show reduced divergence, measured by both FST and dXY, relative to allopatric comparisons, across two different regions of the genome. Error bars (indicating 95% confidence intervals) and p values are based on bootstrap resampling.

(E and F) Furthermore, Patterson’s D statistic is highly elevated in these regions, indicative of biased allele sharing in sympatry due to introgression. Error bars (indicating 95% confidence intervals) and p values are based on bootstrap resampling. *p < 0.05, **p < 0.01, ***p < 0.001.
