Fig. 4: Comparison of IBD connection patterns across different groups.

a Heatmap illustrating the number of IBD connections of segment length 8 cM, 12 cM, 16 cM and 20 cM normalized by the number of possible connections between various groups. The number of possible genetic connections is calculated using the formula n₁ × n₂ for connections between two different groups and (n × (n − 1)) / 2 for connections within a single group, where n₁ and n₂ represent the number of individuals in each group, and n is the number of individuals within a group, following the method suggested by Ringbaur et al 2024. The values range from blue (low connection) to yellow (high connection), indicating the strength of the connections. b Bar plot showing the normalized number of IBD connections for different groups in the Lech valley, categorized by Únětice and Unterwölbling. The x-axis represents different groups, while the y-axis shows the number of IBD connections. The colours distinguish between the Únětice and Unterwölbling categories.
