Variance components and clonal repeatability (R_c) estimates for endophyte transmission in Populations I and IV.

Component1	Pop I	Pop IV
${\sigma }_g^2$	0.0177 (0.0033)	0.0269 (0.0049)
${\sigma }_{gl}^2$	0.0030 (0.0011)	0.0048 (0.0011)
${\sigma }_{\epsilon }^2$	0.0106 (0.0008)	0.0055 (0.0009)
Rc	0.82	0.92

¹Variance components (standard errors in brackets): ${\sigma }_g^2$ = genotypic; ${\sigma }_{gl}^2$ = genotype-by-site and ${\sigma }_{\epsilon }^2$ = experimental error. If the variance component of a model term is more than two standard errors from zero, then the variance component is considered significant (P < 0.05). This is the case for all variance components shown here.
