Rate of IBD Segments along the Autosomes in UK Biobank White British Data

The x axis shows position along each chromosome. Chromosomes alternate in color. Notable genes and regions (LCT, MHC, OAS, and TRPM1) located within the four highest peak regions are labeled. The y axis is the IBD rate, which is the percentage of pairs of haplotypes for which the position on the chromosome is covered by an IBD segment with length >2 cM for the haplotype pair. IBD segment endpoints are posterior medians. The IBD rate is calculated at 10 kb intervals. The black dashed lines show the thresholds of 0.025% and 0.021% used for the results in Tables 1 and 2, respectively.
