Values are least-squares (adjusted) means ± s.e.m.(N=48).
P-values are for two-tailed tests comparing Control and Selected lines.
Data were analyzed by mixed-model nested ANCOVA in SAS Proc Mixed version 8. The effect of line type (selected vs control) was tested over replicate lines nested within line types (d.f.=1,6), and replicate lines were considered a random factor nested within line type. Age was entered as a covariate and `mini-muscle' was entered as an additional factor in all analyses; neither was ever statistically significant (all P>0.05).
If one statistical outlier is removed, the line type effect becomes significant (P=0.0325).
