M2_AFH	4,605,905	− 178,921	47.03	102.10	28.46	24.35	0.51	0.14	0.12
M1_HL	211,323		119.60			76.51			0.39

∆AIC: difference in AIC between M2 and M1, ri²: proportion of the variance due to rider effect, c²: proportion of variance due to the permanent environment effect, and h²: heritability estimate
*Standard errors ranged from 0.004 to 0.02
