Figure 2. — Identification of first-generation trees. In this example, the aggregate signal frequency vector is consistent with three first-generation trees , and . Each first-generation tree is visualized as a matrix equation according to Equation (2) (left) and as a partial evolutionary tree (right). In the bottom row, the partial tree PT₁ given by the union of the partial trees T₁ and T₃ is shown. Question marks indicate values that are unknown as they are not specified by the first-generation tree or by the partial tree.
