Extended Data Fig. 4: IBD0 proportion among sibling pairs across chromosome 1.
From: Mendelian imputation of parental genotypes improves estimates of direct genetic effects
We show the proportion of sibling pairs, out of 19,290 pairs, that are called as IBD0 for each SNP with MAF>1% on chromosome 1 on the UK Biobank genotyping array. We compare the fraction of pairs that are called IBD0 by snipar (black line) and KING (gray line). The theoretical expectation according to Mendelian segregation is 0.25, indicated by the red horizontal line.
