Fig. 4.

Frequencies of each of the 15 putatively adaptive insertions in the 22 Drosophila suzukii populations. Insertion number is indicated on the left together with the associated BayPass statistics. XtX corresponds to a global differentiation statistic, C₂ to a statistic contrasting allelic frequencies between native populations and populations of the invasive American road (${\mathrm{C}}_2^{\text{Am}}$) or populations of the invasive European road (${\mathrm{C}}_2^{\text{Eu}}$) or all invasive populations (${\mathrm{C}}_2^{\text{WW}}$).
