Structure clustering results. A: Membership coefficients of all individuals for K = 7. Bayesian clustering based on seven markers, which include molecular form, the 2La, 2Rj, 2Rb, 2Rc, 2Rd, and 2Ru inversions. Each vertical line represents a single individual. Different colours represent different clusters (= forms). The green colour corresponds to Forest-M form, light-blue to Forest-S form, yellow to Godola-S form, blue to Savanna-S form, purple to Bamako-S form, red to Mopti-M form bc/bc homozygotes, and orange to the "other" Mopti-M forms. Individuals are ordered such that the latitude of collection sites increase from left to right. The latitude and longitude of each collection site are indicated on top of the bar plots and the names of the collection sites are indicated below the bar plots. The associated karyotypes are summarized in Table 2. B: Membership coefficients for K = 4 clustering based on microsatellite markers. The green colour corresponds to Forest-M form, light-blue to Forest-S form, Blue to all other S forms, and red for Mopti- M form. Note that separation of Godola-S, Savanna-S and Bamako-S were not supported at K = 4. C: Membership coefficient for K = 5 clustering based on microsatellite markers. The color scheme is similar to Figure 3B, with the addition of the Bamako-S form indicated in purple.
