Figure 3From: Evolution of endogenous retroviruses in the Suidae: evidence for different viral subpopulations in African and Eurasian host speciesUnrooted Bayesian inference for env class A gene. For clarity, posterior probability values are not represented, but all main groups showed a value of 0.99 to 1.00. Black symbols represent ERVs from the different Eurasian species and gray symbols represent ERVs from different African species (see legend for detail in coding).Back to article page
