Table 2.
f4-statistics for hybrid samples (X) with M. putorius outgroup (W)
| W | X | Y | Z | f4 | Z-scores |
|---|---|---|---|---|---|
| OG | NPC | East | Beringia | 0.30 | 31.79 |
| OG | NPC | West | East | 0.32 | 76.99 |
| OG | NPC | West | Beringia | 0.51 | 70.42 |
| OG | SYT | East | Beringia | 0.13 | 9.29 |
| OG | SYT | West | East | 0.37 | 86.48 |
| OG | SYT | West | Beringia | 0.41 | 42.17 |
| OG | YTAK | Beringia | East | 0.28 | 27.12 |
| OG | YTAK | West | East | 0.40 | 90.67 |
| OG | YTAK | West | Beringia | 0.08 | 10.18 |
F4(W,X:Y,Z) results for each hybrid sample (NPC North Pacific Coast island, SYT Southern Alaska-Yukon border, and YTAK northern Alaska-Yukon border) relative to all possible parental source populations (East, West, Beringia)
All Z-scores are positive for ease of interpretation and significant (>5). Rotating the order of a pair (e.g., YZ to ZY) switches the sign +/− of both the f4-statistic and the Z-score but does not change the relationships
