BSFG estimates of individual trait heritability are accurate. The heritability of each individual trait was calculated as $h_i^2=G_{ii}/P_{ii}$. $\text{RSME}=\sqrt{\left(1/p\right){\displaystyle {\sum }_{i=1}^p{\left({\widehat{h}}_i^2-h_i^2\right)}^2}}$ was calculated for each simulation. Box plots show the distribution of RMSE values for each scenario. (A) Increasing numbers of simulated factors. (B) Different types of R matrices. (C) Different numbers of traits. (D) Different numbers of sampled individuals.
