REML estimates of heritability of Q1. (a) The relationship A of genome-wide SNPs was used to estimate the relationship G at unobserved causal SNPs. Over the 200 replicates, the average heritability estimate was μ = 0.4618 with standard error σ = 0.0999 after correcting for age, sex, and smoking status. (b) The calibrated relationship A* was used to estimate the relationship G at unobserved causal SNPs. Over the 200 replicates, the average heritability estimate was μ = 0.5351 with standard error σ = 0.1206 after correcting for age, sex, and smoking status.
