Body Composition
After weaning (3 weeks of age), F1 and F2 mice were weighed weekly for 40 weeks. Final body weight was recorded at the time of euthanasia. Wet weight was recorded for adipose deposits on the right abdomen and the left kidney. To determine differences in body composition, ratios of bodyweight to adipose mass (body weight/fat pad mass) and bodyweight to kidney mass (body weight/kidney weight) were calculated and compared using a one-way ANOVA (p-value < 0.05).
