Extreme divergence of marker C2_At1g73180. a) Clustering at marker C2_At1g73180 showed the distinctiveness of PI 129026 and PI 196297 with 99% bootstrap support, b) the splits network showed a combination of introgression of PI 129026 and PI 196297 (among others, see Table 2) with S. pimpinellifolium and retention of ancient polymorphisms that reticulated down to the root; the latter supported genetic hitchhiking and rejection of selective neutrality.
