a2 Indicates additive genetic variance; ADE, model including a2, d2, and nonshared environmental (e2) components; BM, best‐fitted model according to Akaike information criterion; BMI, body mass index; d2, dominant genetic variance; Hip, hip circumference; rA, additive genetic correlation; rD, dominant genetic correlation; rE, nonshared environmental correlation; rP, phenotypic correlation; SNP, single‐nucleotide polymorphism–based genomic relatedness matrix restricted maximum likelihood model; WC, waist circumference; WHR, waist/hip ratio.
a
Bivariate d2 and rD are not significantly identified from SNP models for any pairs.
b
Statistically significant estimates (P<0.05).
