Figure 4. Density distribution maps of different kinship parameters. (A) presents the density distributions of IBD parameters (with bin width of 0.1), including k₀, k₁, k_2, and proportion IBD; (B) demonstrates the density distributions of IBS parameters, including IBS₀ (with bin width of 0.1), IBS₁, IBS_2, and normalized cumulative IBS; (C) displays the distributions of log₁₀(LR) values under different hypotheses. The vertical dashed lines represent the median value of the correspondence relationships. IBD: Identity-by-descent; IBS: identity-by-state; FS: full siblings; PO: parent-offspring; 2ND: 2nd-degree relatives; UN: unrelated individuals.
