Figure 3
A, B & C. Phylogeny of the Rhox2 (A), Rhox3 (B) and Rhox4 (C) paralogues. The numbers shown along each branch are the maximum likelihood estimates of the ratio of nonsynonymous and synonymous substitutions for the entire gene along that branch. Data for a "free-ratio" model is shown which allows for a different dN/dS ratio (parameter ω) for each branch in the tree. Branches are drawn in proportion to estimates of their lengths.
