Summary of the four SCA models fit.
| Model | Description | Parameter Constraints |
|---|---|---|
| 0 | No viability selection Male allele frequency constrained |
SRR = SRA = SAA Z terms determined by q and S terms |
| 1 | No viability selection Male allele frequency unconstrained |
SRR = SRA = SAA Z terms not determined by q and S terms |
| 2 | Viability selection allowed Male allele frequency constrained |
SRR ≠ SRA ≠ SAA Z terms determined by q and S terms |
| 3 | Viability selection allowed Male allele frequency unconstrained |
SRR ≠ SRA ≠ SAA Z terms not determined by q and S terms |
