Distances within the wild mouse reference dataset. A) Between-group-PCA scatter plot of the first two PCs. B) Shape changes along PC1 and PC2 (from gray to red in positive direction). C) Distance categories - all pair wise distances within a category are plotted. Only the category "M. mac /M. spre intraspecific" represents two comparisons - the lower point the M. macedonicus and the upper point the M. spretus intraspecific distances between the two populations each. Whiskers represent range of observed correlations.
