Reliability of results in sibship cases

Abstract

Genetic exclusion of siblinghood of two persons, without parental findings, is basically not possible. Both the positive and the negative proof of descent can only be provided by statistics. Our aim is to evaluate the likelihood ratio (LR) and posterior probability (W-value) sufficient for a secured statement. Further, we evaluate the influence of the number of analysed STR systems on the LR-value by analysing different numbers of loci for 1225 unrelated couples and 61 pairs of full-sibs and testing the hypotheses full sibs versus half sibs versus unrelated.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
