Estimated distribution of ROH for ancient samples, placed in the context of values from modern populations. This plot shows total length of ROH for a series of length categories in 32 modern and 6 ancient individuals. Of these modern individuals, 18 were selected from a subset of 1000 Genomes populations (33) with no evidence of recent historical admixture. These individuals represented the median value of total length of ROH for their population. Thirteen modern individuals from the Simons Genome Diversity Project (34) were also included. ROH calls for each sample were based on 1.6M autosomal transversions with minor allele frequencies above 0.5%.
