Individuals overlapping with the 1240k panel and possessing more than 200,000 single nucleotide polymorphisms were included. a, Inferred ROH for Fujia_N and Fujia_S individuals are presented. Expectations are provided for inbred individuals ranging from second-degree relatives to first–third cousins, as well as for individuals from small populations of varying sizes. The ROH length distribution for Fujia corresponds to that expected from a small population size. Asterisks denote individuals with short ROH segments (<8 cM) whose cumulative length exceeds 40 cM. b, The average number of ROH segments across various length categories in Fujia individuals (n = 33). Fourteen highly consanguineous individuals were excluded on the basis of the presence of ROH segments longer than 20 cM and totalling more than 50 cM. Vertical error bars represent ±1 s.e.m. for each length bin (2 cM). The dashed lines illustrate the expected distribution of ROH for various effective population sizes (Ne). c, Estimated effective population size of Fujia and other ancient East Asian populations, indicating Fujia had a small population size. Black points represent maximum-likelihood estimates, with vertical error bars indicating 95% confidence intervals. Sample sizes (number of individuals analysed per site) are annotated above each corresponding point. YR, Yellow River; WLR, West Liao River; EN, Early Neolithic; MN, Middle Neolithic; LN, Late Neolithic.
