Chromosome-wide IBD Segment Detection in the UK Biobank

The methods were run on 5,000 UK Biobank samples on chromosome 1 and chromosome 20 in order to detect identity by descent (IBD) segments having length ≥2 centiMorgan. Each chromosome is divided into non-overlapping 10 kb intervals. For each interval, all IBD segments (from all pairs of individuals) that intersect the interval are each weighted by the proportion of the 10 kb interval that is covered by the IBD segment, and the sum of the weights is plotted as the IBD coverage.
