All-against-all heatmap of clonal connection scores between all B cell subsets for both children. Clonal connection scores range between 0% (lowest in blue) and 4% (highest in red). The highest clonal connection scores are seen within IgM⁺ and IgG⁺ subsets of each child, indicating that samples have not been mixed. To be able to visualize low clonal connection scores between donors, the clonal expansion scores (within B cell populations) have been removed
