Variation was very well resolved for both sexes (although more clearly for females than males), as eigenvalues for the first three canonical roots were well above 1 (males: root 1 = 55.9; root 2 = 16.0; root 3 = 11.3; females: root 1 = 366.9; root 2 = 282.9; root 3 = 6.5) and about two-thirds of the variation was explained in the first root (67%) for males, whereas just over half (56%) was explained in the first root for females. However, cumulatively the first two roots explained 86% of variation in males and a massive 99% in females.
