Fig. 6: Trans-species polymorphisms and evidence of balancing selection at dsx.

a Unique and shared SNPs across the dsx (gray box) region. Vertical boxes E1–6 indicate the dsx exons. Color variation in dots is due to overlapping points. Species combinations not shown had no shared SNPs. b Genome-wide Tajima’s D distributions. Red arrows indicate the highest Tajima’s D value for dsx windows.
