Figure 1. — a) A phylogenetic network on five taxa, with taxon missing (due to extinction or incomplete sampling), and a hybridization involving (ancestors of) taxa and . Shown within the branches of the phylogenetic network is a tree of a recombination-free locus whose evolutionary history includes introgression. b) The gene tree that would be estimated, barring inference error, on the locus illustrated in (a). c) An abstract depiction of the phylogenetic network of (a) given that taxon is missing.
