Family Finder Matching 5.0 introduces an updated algorithm for identifying shared identity-by-descent (IBD) segments and estimating genealogical relationships from autosomal DNA. This white paper describes the matching algorithm, segment detection methodology, centiMorgan thresholds, and relationship probability inference used in the fifth version of FamilyTreeDNA's autosomal matching system.
