Phylogenetic analysis of the C-alpha gene, HS3, HS1.2 and HS4 enhancers. Unrooted phylogenetic trees for C-Alpha (A), HS3 (B), HS1.2 (C) and HS4 (D). Branch length is scaled according to the evolutionary distance, shown as the number of base substitutions per site. The percentage of 100 replicate trees in which the taxa clustered together after the bootstrap analysis is shown at the root of the branches when significant (i.e. when higher than 50%). As examples, the value '100' at the base of the separation between the taxa Mus musculus and Rattus norvegicus in panel D means that the two taxa were clustered together in all the replicate trees, while '72' between Homo sapiens and Gorilla gorilla in the same panel means that 72% of the 100 replicate trees clustered these two groups together.
