Table 3.
Characteristics of genomic islands of divergence for each of the four whitefish species pairs. See §5 for detailed explanations of how each parameter was defined.
| mean FST | AFLP outliers | QTL outliersa (number of islands) | relative size of islandsb | outlier threshold (sea level) | height of island | |
|---|---|---|---|---|---|---|
| East L. | 0.05 | 4 | 4 | 1.00 | 0.25 | 0.08 |
| Indian L. | 0.04 | 9 | 3 | 1.43 | 0.20 | 0.08 |
| Webster L. | 0.10 | 5 | 1 | 1.57 | 0.37 | 0.18 |
| Cliff L. | 0.14 | 14 | 7 | 1.95 | 0.46 | 0.29 |
aNote that QTL outliers are the sum of both BCD and BCN pQTL and also outliers in natural populations.
bSizes are based only on BCD map. They represent the x value where y is equal to the mean FST value for a given species pair in figure 1. Sizes are then divided by the value for the least divergent lake (East) in order to get among lake relative estimates.
