Extended Data Fig. 9: Population genetic analyses of Gurgy individuals.
From: Extensive pedigrees reveal the social organization of a Neolithic community
a, Principal component analysis. Published ancient (symbols with no outline) and Gurgy (black outlined symbols) individuals projected onto 777 present-day west Eurasians (grey circles; Supplementary Note 10). b, Genetic ancestry proportions. Results of qpAdm (MODEL 1) ancestry modelling of Loschbour hunter-gatherer and Anatolia_Neolithic ancestry for all Gurgy individuals (Supplementary Note 10). c, Runs of homozygosity. Selected individuals with more than 300,000 SNPs on the 1.2 million SNP panel (n = 86) and simulated data expected for inbred individuals from parents related at the first- to third-degree, and for individuals from small populations with different sizes. Individual GLN282 shows an inbreeding signal similar to a first-cousin union, but both carried ROH are 20–22 cM long, therefore this individual is more plausibly the offspring of second or third cousins (Supplementary Note 4, Supplementary Table 1).
