Hypothesized hybridization scenario. (A) Phylogenetic network estimated with SNaQ showing the tetraploid C. erinus and C. creutzburgii as putative parental lineages of the octoploid C. erinus (dashed lines). Numbers on dashed lines indicate inheritance probabilities from SNaQ analysis. These values represent the proportion of the genome estimated to have been contributed by each parental lineage. To simplify the figure, we have collapsed the C. creutzburgii lineages (found to be reciprocally monophyletic) to a single lineage. (B) Depiction of the hypothesized hybridization event indicating maternal and paternal genomes involved in the allopolyploid event. Large circles represent nuclear genomes while smaller squares represent plastomes. Red and purple colors indicate parental contributions from each tetraploid.
