Transmission of SARS-CoV-2 in domestic cats imposes a narrow bottleneck
Fig 2
Within-host diversity of SARS-CoV-2 viruses in domestic cats.
A) Plot representing all variants (iSNVs and indels) detected in any cat at any timepoint. Variant frequencies are plotted by genome location and are colored by gene. Circles represent synonymous iSNVs, squares represent nonsynonymous iSNVs, and stars represent indels. B) iSNV frequency spectrums with error bars showing standard deviation for index cats plotted against a “neutral model” (light gray bars) which assumes a constant population size and the absence of selection.
