  1. Io is the "old" internal insect branch, In is the "new" internal insect branch, Ag indicates the terminal branch leading to Anopheles gambiae, Aa indicates the terminal branch leading to Aedes aegypti. The relative branch length was calculated as the ratio of the length of the analyzed branch to the total length of all involved branches averaged over 255 sampling experiments (complete sampling) or from restricted sampling with at least 2 or 3 outgroup species. Normalized number of reversals is the number of reversals divided by the branch length.
