MAR: Estimates of ${\mathit{\sigma }}_A^2$, ${\mathit{\sigma }}_C^2$ and $h^2$ of both approaches when 2, 6 and 10 % of the covariate data were missing. Dotted lines full information approach. The horizontal lines denote the true values of ${\mathit{\sigma }}_A^2$, ${\mathit{\sigma }}_C^2$ and $h^2$
