Heatmap of probabilities (× 1000) of between individual sharing of > 7 cM segments within and among populations. Ancient population data (shown red) include data for Sint-Truiden and Ypres from this study, Early medieval (EMA) data from Gretzinger et al. 2022 [ 5 ], Sasso et al. [ 6 ], Late Iron Age (LIA) genomes from Fischer et al. 2022 [ 22 ], Viking Age (VA) data from Margaryan et al. 2020 [ 8 ], and Roman period data from Scheib et al. 2023 [ 23 ], Martiniano et al. 2016 [ 25 ] and Schiffels et al. 2016 [ 24 ]. Modern reference data include populations from the UK Biobank [ 32 ] and MinE Project data [ 26 , 27 ]. ST-main – 318 genomes from the Sint-Truiden main group; ST-out—five outliers identified by PCA (Fig. 2 ).
