p-values for the different association tests (the LQ has been analyzed using an ANOVA, while handedness groups, handedness direction and degree of handedness have been analyzed using Kruskal-Wallis-tests).

Effects significant at the pNote: * = pThe p-values for all genotype group comparisons for LQ, handedness groups (consistent left-handers, inconsistent left-handers, ambidexter with a tendency towards left-handedness, ambidexter with a tendency towards right-handedness, inconsistent right-handers, consistent right-handers), handedness direction (left, right) and degree of handedness (consistent, inconsistent).
