μ indicates mean; σ, standard deviation; h², residual heritability; β, estimated mean effect of significant (P < .10) covariates; —, covariate not included in final genetic model for trait because mean effect was not significant (P > .10); c², proportion of total trait variance due to significant covariates.

^*P (h² = 0) < .01 for all traits except MCHC, where P (h² = 0) < .05.
