Assumptions about species replication in our model
| Duplication mechanism | Death rate | Rate-determining gene no. | |
|---|---|---|---|
| Bacteria | Semiconservative, mutations could happen to both descendant copies | Negligible | Large (20 ∼ 300) |
| DNA virus | Semiconservative (mostly), mutations could happen to both descendant copies | Nonnegligible | Small (∼20) |
| RNA virus | Conservative (mostly), mutations happen to only one descendant copy, and a master genome is preserved | Nonnegligible | Small (∼20) |
