Genetic covariances (genetic correlations ± SE) between daughters' pronotum width, brood mass weight, and brood mass number between traits

	Pronotum width	Brood mass weight	Brood mass number
Pronotum width		1.31 × 10−3	9.69 × 10−3
		(2.579 ± 9.740)	n/a
Brood mass weight	3.77 × 10−3		12.30 × 10−3
	(0.155 ± 0.229)		n/a
Brood mass number	15.46 × 10−3	29.15 × 10−3
	(−0.029 ± 0.099)	(−0.076 ± 0.148)

n/a, Genetic correlations can not be calculated because of negative variance caused by sires (Table 1). Sire (narrow sense) estimates above the diagonal, dam (broad sense) estimates below the diagonal.
