Fig. 2.

Phylogenetic analysis of 114 mysTR elements from eight rodent species, four L1 active (blue branches) and four L1 inactive (red branches). The unrooted Bayesian tree was constructed using an average of 890 bp of the pro/pol region. Selected posterior probabilities are indicated on branches. Names of individual elements have been removed, and the species from which each clade or element originated are shown. All species except S. hispidus have two lineages of mysTR elements. “C” denotes a putative root of the tree.
