  • For each IBS mode, the number of different genotypes possible in that mode is indicated in the column labeled “count.” The genotypic category to which each IBS mode belongs is listed, as are the mode's value of SXY and single-locus Lynch–Ritland (LR) and similarity index (SIM) estimates for the coancestry coefficient based on that mode.
