  1. \(\widehat{\psi }\) is the estimate of the two siblings’ unobserved fraternity coefficient \(\psi\). (*) Unadjusted values from LowKi, similar to in Additional file 1: Fig. S2. (**) The time required for these estimators is almost entirely due to BEAGLE, both LowKi and SEEKIN require only a few minutes. (†) SEEKIN does not provide estimates of \(\psi\). (‡) NGSRelateV2 results on down-sampled data should be compared to results from the same software but applied to the original data that had not been down-sampled
