Traza DNA Treats the Family Tree as a Testable Hypothesis
A genetic-genealogy research tool that compares competing pedigree hypotheses against autosomal DNA evidence.
Field notes
The workflow combines a user-supplied genealogy with shared autosomal DNA observations, then simulates inheritance separately under competing pedigree hypotheses. The homepage illustrates the interface with three hypotheses receiving 72%, 21%, and 7% support, based on four DNA matches and 10,000 simulations. It also warns that related matches can create dependent evidence and that conclusions remain conditional on the hypotheses, priors, and model assumptions. The application is presented as an invite-only pilot.
