Fig. 6: Inversions involved in local adaptation.

a, FST between forest and prairie ecotypes found in western North America. Grey dots show FST from 100 kb windows, with smoothed FST as black lines. Inversions with allele frequency difference >50% between forest and prairie ecotypes are shown in dark red; inversions with allele frequency difference >10% are shown in pink. b, Inversion or standard arrangement frequencies across an environmental gradient found between the forest and prairie populations, with clines fit using hzar. Sampled populations are shown with black ticks along the x axis, with forest population as the left-most tick and prairie population as the right-most tick. Clines show frequency of the forest allele: an asterisk indicates that the standard arrangement is more common in the forest population; no asterisk indicates that the inversion arrangement is more common in the forest population. A satellite image across the environmental gradient (obtained from GoogleEarth) is shown below, with sampled sites in yellow. c, Inversions with significant associations with tail length or coat colour in a forest–prairie F2 intercross. F2 hybrids are grouped by inversion genotype, with each genotype coloured by whether it is more common in the prairie (tan) or forest (green) population. Sample sizes are shown below the x axes. Data represent means (centre lines) ± s.d. (boxes). P values (Bonferroni corrected) and percentage variance explained (PVE) from linear models, calculated with analysis of variance, are shown for each association. Tail/body, ratio of tail length to body length; coat colour is measured by hue and shown in degrees. inv, inverted haplotype; std, standard haplotype.
