WebTo improve accuracy and precision, we estimate the evolutionary rate using many sequences sampled serially, that is, over time. For each sample in our dataset, the x-axis position is given by the sample collection date, and the genetic divergence between the root sequence and the tip sequence, the root-to-tip distance, gives the y-axis position.

WebAug 11, 2024 · When the strict molecular clock is followed, the true rooted phylogenetic tree is ultrametric with zero root-to-tip distance variance. For ultrametric trees, only the true rooting position is a balance point, and therefore, the tree has a unique local MV at the correct root, which is also its global MV (Proposition 3).
