Averaged estimates of ID from 1,000 simulated datasets. In A datasets were simulated assuming no ID, i.e., and nonnegative expectation for the additive effects (i.e., , for the jth causal variant). In B datasets were simulated assuming no ID and no directional effect of minor alleles but including the contribution of the first 10 genotypic PCs to model the effect of population stratification. , excess homozygosity inbreeding measure; , runs of homozygosity-based inbreeding measures; , measure of inbreeding based on correlation between uniting gametes; SEM, SE of the mean.
