Extended Data Fig. 4. Downsampling of Hazelton pedigree samples.
We downsampled all individuals from a previously published English Neolithic pedigree26 with coverage at least 1x both to 1x and 0.75x. For each coverage, we downsampled 10 times, each with different random seeds, to create 10 replicates. Therefore, not all dots are independent pairs of relatives; they may be the same pair downsampled with different random seeds. The relationship annotations are obtained from Supp. Table 5 of ref. 26. All relatives more distant than 3rd degree are depicted as hollow dots.
