Figure 1. Genetic mechanisms of viral diversity and genomic sequencing strategies.
(A) Example of recombination between ssRNA virus genomes (i.e., dengue) and reassortment between segmented RNA virus genomes (i.e., influenza A) coinfecting the same cell. (B) Schema of how consensus sequencing provides a homogeneous representation of a virus population while deep sequencing generates sequence reads that capture genetic diversity, but that may not be unambiguously assembled into individual genomic segments.
