Table 1 Frequency of recombination events detected in 229E, NL63, OC43, HKU1, MERS-CoV, SARS-CoV1 and SARS-CoV-2, stratified by level of evidence.
Coronavirus species | n genome sequences | Recombination events detected by any method | Recombination events detected by ≥ 3 methods | Recombination events detected by ≥ 3 methods and without another evolutionary process possibly explaining the recombination signal (high evidence) | Recombination events with high level evidence seen in multiple genomes |
