Table 3.
Results of Mantel tests (r and P-value) for pairwise populations with four distances calculated: neutral genetic distance (FST), geographic distance (ln-transformed), flower colour distance (Euclidean distance of the weight-mean reflectance ratio) and flower size distance (Euclidean distance of the PC1 co-ordinates, see text for details)
| Distance 1 | Distance 2 | All of the populations (37 populations) |
French populations only (32 populations) |
Spanish populations only (five populations) |
