Figure 4From: Cyto-nuclear discordance in the phylogeny of Ficus section Galoglychia and host shifts in plant-pollinator associationsThe cyto-nuclear discordance explained by ITS and ETS duplication-extinction. The scenario requires a basal duplication (D) followed by three extinction events: one extinction of allele 1 (E1) and two extinctions of allele 2 (E2).Back to article page
