Transmission of SARS-CoV-2 in domestic cats imposes a narrow bottleneck.
The evolutionary mechanisms by which SARS-CoV-2 viruses adapt to mammalian hosts and, potentially, undergo antigenic evolution depend on the ways Outdoor Armless Chair with Cushion genetic variation is generated and selected within and between individual hosts.Using domestic cats as a model, we show that SARS-CoV-2 consensus sequences remain largel
