Fig. 5

Boxplot representations of HERV-W subgroups divergence based estimated period of integration. The approximated age (in million years) was calculated considering the divergence values between the 5′- and 3′ LTRs of the same provirus (only for proviral sequences); between each LTR and a generated consensus for each subgroup and between a 150–300 nucleotides region of each HERV-W internal element gag, pro, pol RT, pol IN and env genes and a generated consensus (proviruses and pseudogenes). a Averaged values of age obtained for each sequence, after the sequences division in proviruses and pseudogenes for each subgroup. b Single method estimations for the two HERV-W subgroups. c Highlight of the heterogeneous action of the divergence at different genic regions
