Inbreeding depression across the genome of Dutch Holstein Friesian dairy cattle

Table 4 Estimates of relative dominance variance from various studies that used genomic relationship matrices

Study	Density	Accounted for GW ID^a	Relative dominance variance
Aliloo et al. [14]	632 k (imputed)	Yes	≤ 1% for yield traits
Aliloo et al. [14]	632 k (imputed)	Yes	1% for calving interval
Aliloo et al. [14]	632 k (imputed)	No	3 to 4% for yield traits
Aliloo et al. [14]	632 k (imputed)	No	1% for calving interval
Sun et al. [35]	50 k (imputed)	Yes, in precorrection of phenotypes	3 to 4% for yield traits
			1% for SCS
			0% for daughter pregnancy rate
Jiang et al. [43]^b	50 k (imputed)	No	7 to 13% for yield traits
			0 to 15% for fertility traits
			9% for SCS
Alves et al. [44]	41 k (imputed)	No	0 to 4% for fertility traits
Mao et al. [45]	36 k	No	7% for interval first-last insemination
Mao et al. [45]	36 k	No	4% for number of inseminations

^aGW ID: genome-wide inbreeding depression
^bIn this particular study, an imprinting effect was also fitted. All other studies used AD models
