The small differences in percentages (say, 98.6% vs. 99.9%) have to do with the strength of the genetic matches. A paternity exclusion indicates that the tested man is not the true biological father of the child, for example. There is not a whole lot of research online regarding relationship tests, so Im confused how many of the markers should match and/or what the combined index should calculate too in order for a relationship to be established.
