Pairwise IBD coefficients (k0 versus k1) estimated by the PLINK method of moments. Plus symbols indicate theoretical values for PO (k0 = 0, k1 = 1), FS (k0 = 0.25, k1 = 0.5) and HS (k0 = 0.5, k1 = 0.5) relationships. Points are coloured according to the assigned type of relationship: PO (blue), FS (brown), HS and higher degrees of relationship (orange). The discrimination between FS and HS was based on an arbitrary-chosen conservative threshold of k2 = 0.25.
