Table 2.

Sharing of IBD segments longer than 7 cM among imputed Koksijde genomes

Note that numbers of shared >7 cM IBD segments are shown below the diagonal and the degree of relatedness inferred with IBIS (17) above the diagonal.

No_rel—total number of related individuals who share at least 2 IBD segments (>7 cM) in the sample.

Gaulish_a—proportion of Gaulish ancestry inferred with qpAdm (SI Appendix, Table S6, model using French Gaul and Early Medieval Netherlands as sources).

^*Genetic outliers in PCA (Fig. 1).

^†KOS007 shared only a single >7 cM segment internally within the Koksijde sample (with KOS015) while sharing multiple segments externally with three English (ELY001, ELY002, and I16508) and one German (IND017) Early Medieval individuals. No other Koksijde individual shared multiple >7 cM segments externally.
