Estimated expected age of the MRCA (T̂MRCA) under a model of exponential population growth
| Gene | T̂MRCA, in N0 generations | T1g | T2g | T̂MRCA, years | T1y | T2y |
|---|---|---|---|---|---|---|
| SMCY | 0.0731 | 0.0618 | 0.1030 | 48,000 | 41,000 | 68,000 |
| DBY | 0.0538 | 0.0382 | 0.0975 | 55,000 | 39,000 | 100,000 |
| DFFRY | 0.0582 | 0.0440 | 0.0720 | 53,000 | 40,000 | 65,000 |
| Three genes | 0.0853 | 0.0580 | 0.2070 | 59,000 | 40,000 | 140,000 |
The 95% central probability intervals (T1g, T2g) and (T1y, T2y) are for time in units of N0 generations and years, respectively, using 25 years per generation.
