RT-based neighbor-joining tree for Class I murine retrotransposons. The distances (uncorrected 'p') appear next to each of the branches. RT sequences from host species other than mouse are included for comparison. The outgroup is the Class II element GH-H18 (from golden hamster, Mesocricetus auratus; see Table 3 and Figure 3).
