Figure 3: Geographic locations of subspecies collections and inversion zone genotypes.
From: Young inversion with multiple linked QTLs under selection in a hybrid zone
a, Species-wide samples, with each dot indicating one genotype from a population. Subspecies assignments show East (blue) and West (red). The ellipse indicates the contact zone where subspecies overlap, and the star shows the inversion zone. N = 83 genotypes. The collinear cross comes from within the hybrid zone (ellipse), but outside the inversion zone (star). b, Close-up of populations near the inversion zone, with pie diagrams indicating the inversion frequency (red) in each population, sized in proportion to sample size. Forested, unsuitable habitat probably limits gene flow. N = 122 genotypes. Individual populations ranged in size from 1 to 19. Map image in b: © 2017 Google – Map Data.
