Differences in size, shape and allometry among the different geographic origins of wild boar, among the different breeds of domestic pig, and between wild and domestic pigs. Results correspond to the statistic of the tests (Kruskal-Wallis (X2), Wilcoxon (W), and analysis of variances (F)) paired with the corresponding probability (p). Degrees of freedom are mentioned in brackets. Results in bold are significant after correcting for multi-test comparisons.
