Fig 2.

The position of apomictic triploid hybrids relative to parental species (split by reproductive mode) in genetic space. Principle components reveal that apomictic diploid lineages are more likely to sire triploid lineages than diploid sexual conspecific lineages in two comparisons: B. stricta X B. retrofracta (upper panel), B. stricta X B. pendulocarpa (lower panel) PCA scores for the 1^st two axes and 95% confidence ellipses are plotted. As in fig 1, triploids are pink and diploid apomicts are blue.
