Differences in heritability for 200 GAW17 family data replicates using affection status with quantitative phenotypes added as a covariate where the β coefficient is constrained for the quantitative trait versus where the β coefficient is allowed to fluctuate in a polygenic model. (a) Phenotype Q1 (average difference = 0.061 [± 0.08]); (b) Q2 (average difference = 0.118 [± 0.085]); and (c) Q4 (average difference = 0.022 [± 0.033]).
