Males weigh more than females only at older ages. A repeated measures ANOVA of weight with age as a repeating factor demonstrated a significant interaction between sex and age. Bonferroni post hoc analysis revealed significant differences between males and females at PN34, PN36, and PN38 (two-way repeated measures ANOVA with Bonferroni post hoc: **p < 0.01, ***p < 0.001). The percent difference between males and females is noted above each pair of data points
