^aEstimates (SE) of parameters retained in the final model (the final estimate of h²_g is given even when = 0). σ²_g, autosomal additive genetic variance; σ²_mt, additive genetic variance due to the mitochondrion; σ²_Xf, X-linked additive genetic variance in females; σ²_ef, random environmental variance in females; σ²_em, random environmental variance in males.

^bSEs reported as (0.00) are nonzero but <0.01.

^cp < 0.01
