Figure E2: IBD sharing matrix of various Copper & Bronze Age West Eurasian Groups for four IBD length scales.

As in Fig. 5, but for shared IBD [8 − 12 cM], [12 − 16 cM], [16 − 20 cM], >20 cM long. We used ancIBD to infer IBD segments between all pairs of groups and visualize the fraction of pairs that share at least one IBD for each pair of populations and for the four different IBD length bins.
