The relationship prediction tools at this site take into account differences between maternal and paternal relationships and show that close genealogical relationships considered to be in the same group are sometimes quite different. Another advantage of this tool is that it works for percentages at 23andMe and for cM values in the range of full-siblings at 23andMe. This tool is the go-to predictor for close family surprises.
