  1. We simulated settings with a moderate negative genetic correlation (MOD), or a high negative genetic correlation (HGC). The last 11 columns show the additive genetic variances of the direct (\({\sigma }_{a}^{2}\)) and maternal effects (\({\sigma }_{m}^{2}\)), their covariance (\({\sigma }_{am}\)), the residual variance (\({\sigma }_{e}^{2}\)), the heritabilities of the direct effects (\({h}_{a}^{2}\)), maternal effects (\({h}_{m}^{2}\)), the genetic correlation (\({r}_{G}\)), the genetic variance of the worker groups (\({\sigma }_{W}^{2}\)), the genetic variance of the queens (\({\sigma }_{Q}^{2}\)), and the heritabilities of the sum of the maternal and direct effects of the worker groups (\({h}_{CBS}^{2}\)) and queens (\({h}_{GPS}^{2}\)), respectively
