Figure 1

The reconstruction accuracies from all the leaves as well as from a root-to-leaf path in an equal-branch complete binary tree T _n with n large for 2, 4, 5 and 20 states models. UA and AA denote the unambiguous and ambiguous accuracy respectively by using all the leaves. Figure 1 (a)-(d) show the trend of reconstruction accuracies with the increase of conservation probability for the number of states 2, 4, 5 and 20, respectively. The dashed line denotes the unambiguous reconstruction accuracy by using all the leaves, the solid line denotes the ambiguous reconstruction accuracy by using all the leaves, and the diamonds the unambiguous and ambiguous accuracy by using any root-to-leaf path. Note that the unambiguous and ambiguous accuracies by any root-to-leaf path are the same.
