HybridSim Parameters for the Simulations.
| Example 1 | Example 2 | Example 3 | Example 4 | |
|---|---|---|---|---|
| Number of gene trees | 50 | 150 | 10 | 106 |
| Number of Hybrid speciations | 0 or 2 | Variable | 0–3 | |
| Hybrid and introgr. Rate | N/a | (0,0.1,0.26,0.4) | N/a | |
| Hybridisation success | Always | Linear, threshold T = 1.3 | Always | |
| Coalescence rate | 5 or 15 | (6,10,30,1000) | 2–200 | |
| Hybrid gene contribution | 50:50 | 75:25 | 50:50 | |
| Introgression gene contribution | N/a | 90:10 | N/a | |
| Number of taxa | 10 | 20 | 8 | |
| Number of simulations | 2,000 | 1,000 | 100,000 | |
Note.—Speciation rate is 1 in all simulations, so all other rates are given relative to the speciation rate. Example 4 is an ABC analysis of the Rokas et al. (2003) data for eight yeast species.
