Relationships among Alloteropsis lineages. (A) The phylogenetic relationships among the main lineages of Alloteropsis are shown, based on the nuclear genome analyses by Raimondeau et al. (2022). The approximate age of the root is indicated, and the names of the group and their photosynthetic types are given on the right. Abbreviations: Dec, decumbent; Ere, erect. Arrows connecting branches indicate reported episodes of genetic exchanges (Olofsson et al., 2021; Curran et al., 2022). (B) The genetic contributions of genetic groups are represented for polyploid individuals analysed in detail (Olofsson et al., 2016, 2021; Bianconi et al., 2020). For each polyploid, the approximate proportion of their genome originating from each diploid lineage (shown at the top) is represented by a corresponding colour. Ploidy levels are indicated on the left, and the name of a representative population is given for each polyploid.
