Evolution of the mimetic Heliconius hermathena color pattern. a Genome-wide FST between mimetic H. h. vereatta and non-mimetic H. h. duckei, calculated in non-overlapping 10-kb windows. bFST between H. h. vereatta and H. h. duckei at the chromosome 15 peak, calculated in 5-kb windows (500-bp step). c Genome-wide fd tests for introgression from H. erato hydara into H. h. vereatta, calculated in non-overlapping 10-kb windows. H. melpomene was used as an outgroup. dfd at the chromosome 15 peak. The coordinates of erato-sara clade inversion are also shown (see the “Results” and “Discussion” sections and Fig. S17). e Relative divergence between H. h. duckei and H. h. vereatta to H. erato. a, b Calculated using SNP calls relative to the H. hermathena reference genome while ce calculated using SNP calls relative to the H. melpomene reference genome to reduce reference bias. For consistency, all results are plotted relative to the H. melpomene reference genome, and all coordinates and gene models are based on the H. melpomene genome (the “Materials and methods” section). f Maximum likelihood tree based on the variation in the cortex region with high FST between mimetic and non-mimetic H. hermathena (highlighted yellow in b and d). Collapsed clades contain multiple individuals of the same species/subspecies. Only branches with less than 100% bootstrap support are labeled.
