Genome-wide differentiation between A. lyrata diploids and tetraploids, and between tetraploid lineages grouped by biogeography
| Contrast | No. of SNPs | AFD | dXY | Fst | Rho | Fixed Diff |
|---|---|---|---|---|---|---|
| Diploid lyrata vs. lyrata eastern tetraploids (Let) | 2,904,110 | 0.14 | 0.22 | 0.09 | 0.19 | 270 |
| Diploid lyrata vs. lyrata Wachau tetraploids (Lwt) | 3,794,257 | 0.11 | 0.16 | 0.07 | 0.17 | 64 |
| Lyrata Let tetraploids vs. Lwt tetraploids | 4,795,381 | 0.09 | 0.16 | 0.06 | 0.13 | 24 |
| Arenosa Hercynian tetraploids vs. arenosa Alpine tetraploids | 1,812,223 | 0.10 | 0.16 | 0.03 | 0.07 | 0 |
Differentiation metrics shown are allele frequency difference (AFD), dXY, Fst, Rho and the number of fixed differences (Fixed Diff). Multiple differentiation metrics were used, as the metrics exhibit different sensitivities to diversity and differentiation. Values of all metrics were averaged over pairwise comparisons of populations belonging to that group
