Female dominance, sexual dimorphism and percentage of males in the group. Regression analyses (slopes and p-values) for raw data and independent contrasts branch length based on Purvis [80]. For empirical data see Table 4. FemDom = female dominance, SexDim = sexual dimorphism, % Males = percentage of males in the group.
