Figure 2From: Uncovering rate variation of lateral gene transfer during bacterial genome evolutionDifferent insertion/deletion rates were assumed on the phylogeny. Case 1: a single constant rate throughout the phylogeny (μ1 = μ2 = μ3). Case 2: two rates differentiate the Bc group (μ1, μ2 = μ3). Case 3: three rates differentiate the Bc group and the branch leading to this group (μ1, μ2, μ3).Back to article page
