Advanced Segment Mapping
Welcome to the Advanced DNA & Segment Mapping Hub. This track is designed for intermediate to experienced genetic genealogists who want to verify specific ancestral links on Chromosomes 1 through 22. Learn how to configure chromosome browsers, verify triangulated groups, and test relationship hypotheses using advanced statistical models.
Simply sharing mutual matches (the “In-Common-With” filter) does not prove a shared ancestor. True DNA triangulation requires proving that you, Match A, and Match B all share a segment on the exact same chromosome at the identical base-pair positions. Always use chromosome browsers to verify overlaps and avoid chasing “false positive” matches caused by endogamy.
Intro to Chromosome Browsers
BrowsersLearn how to configure chromosome browsers on platforms like MyHeritage, FamilyTreeDNA, and GEDmatch, and how to avoid the “pile-up region” error trap.
