a, The number of WGS samples analysed for phenotypes in our study. b, UMAP plot generated from the first 40 principal components of all UKB participants, coloured by self-reported ethnicity: blue shades for ethnic labels under the white category (XBI), red shades for Black individuals (XAF) and green shades for South Asian individuals (XSA); for the full colour legend, see Supplementary Fig. 17. c, Joint frequency spectrum of variants on chromosome 20 between all pairs of populations. df, Characteristics of the XBI cohort across Great Britain and Ireland are shown: the number of singletons carried by individuals in the XBI cohort as a function of place of birth (d); the mean number of third-degree relatives by administrative division (e); and the location of UKB assessment centres and estimated fraction of the surrounding population recruited to the UKB (f). Differences in singleton counts and the number of third-degree relatives are probably a result of denser sampling of individuals living near UKB assessment centres. Fig. 3d–f by K.H.S.M.
