Typical patterns for evolution of individual clonal waves | Typical patterns for evolution of genetic instability |
---|---|
| |
□1. Stable throughout growth Results from low mutation rates and high death rates Instability is a “passenger” phenomenon |
□1. Instability does not evolve Observed when the death rates are large and mutation rates are low |
◇2. Originates from unstable cells then stabilizes Results from high mutation rates and moderate death rates Instability is a causal event |
□2. Instability is generated but gives way to more stable clones Observed when the death rates and mutation rates are in balance |
◇3. Originates from unstable cells and remains unstable Results from high mutation rates and low death rates Instability is a causal event |
□3. Instability evolves and comes to dominate the system Observed when the death rates are low and mutation rates are large |
