Fig 5. Railway-specific selection on a highly-differentiated railway haplotype of CONSTANS.

(A) Marks of differentiation between one lowland railway population STE (upper panel) or BGS (lower panel) and two mountain populations (HO and KA) evaluated with G_ST across CO region. Dotted lines are respective genome-wide 1% threshold levels. (B) Gene-wise marks of introgression (${\widehat{f}}_d$), railway-mountain differentiation (G_ST), and railway-specific positive selection (Fay & Wu’s H, and Tajima’s D) across CO region. For each gene, only the least extreme values are represented. Dotted lines are $3*{\widehat{f}}_d(KA,BGS,TBG)$ (upper panel) or most extreme genome-wide 5% threshold levels.
