Genetic connectedness with six target populations of the circum-Baltic region and Estonian Bronze Age, Iron Age, and medieval genomes

Each individual violin plot shows the distribution of PiC scores, which reflect individual probabilities of >5 cM LSAI sharing and kinship coefficient estimate higher than 0.0005. Individuals from the modern target population are shown on the y axis. Distributions of the present-day populations are shown by the colors according to the map. Present-day genomes include 99 Finnish individuals from the 1000 GP data; 4,739 EstBB Estonians born before 1940, including 1,880 from Harju, Saare, Viru, Tartu, and Valga counties, and 320 EstBB Latvians, Lithuanians, Belarusian, and Polish individuals born outside Estonia. All ancient samples, shown with squares (medieval), circles (Iron Age), and triangles (Bronze Age), have been imputed, including one medieval 0.1× coverage British genome PSN177 as a control, with 2,092 Estonian high-coverage sequences as a reference panel.
