Selective advantage for conservative viruses.
In this article we study the full semiconservative treatment of a model for the coevolution of a virus and an adaptive immune system. Regions of viability are calculated for both conservatively and semiconservatively replicating viruses interacting with a realistic semiconservatively replicating immune system. The conservative virus is found to have a selective advantage in the form of an ability to survive in regions with a wider range of mutation rates than its semiconservative counterpart, as well as an increased replication rate where both species can survive. This may help explain the existence of a rich range of viruses with conservatively replicating genomes, a trait that is found nowhere else in nature.
