Figure 6.
SARS-CoV-2 comparative genomics. We randomly sampled 10,000 Alpha, Delta, and Omicron genomes from the UK pandemic. As we randomly accumulate genomes, information diversity accrues. We show that Delta and Omicron converge on similar information diversity, but that Delta is more complex. Both are far more diverse than either Alpha or Omicron BA1 alone, an observation confirmed by phylogenetic methods on far fewer genomes.
