Genomic prediction of the polled and horned phenotypes in Merino sheep

Table 4 Testing various modes of inheritance for polled/non-polled (P/NP) and horned/non-horned (H/NH) at the single SNP locus based on Akaike’s information criterion (AIC)

Model^a	P/NP		H/NH
Model^a	AIC	ΔAIC	AIC	ΔAIC
(1) Additive	− 3387	0	− 5070	0
(2) Additive + dominance	− 3580	193	− 5168	99
(3) Sex-dependent additive + dominance	− 3689	302	− 5162	92
(4) Additive + sex-dependent dominance	− 3759	371	− 6871	1802
(5) Sex-dependent additive + sex-dependent dominance	− 3752	365	− 7236	2166
