Figure 5. Gene trees within the branches of a phylogenetic network.

Figure 5

The phylogenetic network, drawn with tubes, fits the evolutionary histories of all genes, including those that evolve vertically (e.g., the gene tree drawn with green lines) and those that involved horizontal transfer (e.g., the gene tree drawn with blue lines, and HGT or introgression events highlighted with red arrows).
