Fig. 5

a Genetic distance among the different species of the O. sphegodes s.l. group plotted along the genome, colours showing the most genetically dissimilar species for a given 1 Mb window (see Supplementary Fig. 17 for genetic similarity). b Genome-wide PCoA plot of pairwise distances between plant individuals revealed genetic separation between the four species. c Global FST among the 4 species was elevated in one region on chr 2 (327–346 Mb, shown as black bar). d PCoA of this region of chr 2 shows increased separation between O. sphegodes and O. exaltata. Colours show the most dissimilar species in panels a and c (grey: no data), and species identity in panels b and d, where O. sphegodes is shown in blue; O. exaltata, O. garganica and O. incubacea are shown in red, green and yellow, respectively.
