Fig. 3

Means and residual standard deviations and coefficients of variation among birth types for birth weights and among birth-rearing types for weaning weights. Means and standard deviations (SD) are expressed as percentage deviations from the reference class (twin-born lambs for birth weight and twin-born, twin-reared lambs for weaning weights). Coefficients of variation (CV) are expressed as absolute deviations from the reference class. ^†, *, **, *** indicate that residual variances or CV differ from those observed for twin lambs at P < 0.10, 0.05, 0.01, and 0.001, respectively, by F-test with Bonferroni adjustment for multiple comparisons
