Figure 3From: Identification, characterization and comparative genomics of chimpanzee endogenous retrovirusesPhylogenetic tree of CERV 1/PTERV1 LTRs. Unrooted neighbor joining phylogenetic tree built from 5' and 3' LTRs from full-length CERV 1/PTERV1 elements. The average pairwise distances (corrected 'p' using Jukes-Cantor model) for each subfamily and the estimated ages are shown. Bootstrap values are shown.Back to article page
