Phylogenetic tree of CERV 2 LTRs. Unrooted neighbor joining phylogenetic tree built from CERV 2 solo LTRs and 5' and 3' LTRs from full-length elements. The average pairwise distances (corrected 'p' using Jukes-Cantor model) for each subfamily and the estimated ages are shown. Bootstrap values are shown.
