Second Parent Ancestry
Using your DNA and one known parent's DNA, we mathematically reconstruct the genetic profile of your untested parent — and deliver a complete 21-page ancestry report with 15 analyses, from Neolithic deep ancestry to modern population matching. Powered by Claude AI (Anthropic).
How It Works
By analyzing your DNA and your known parent's DNA, we mathematically estimate what your other parent's genetic ancestry looks like. This is based on the principle that you inherit approximately 50% of your DNA from each parent.
Other Parent ≈ (2 × Child DNA) − Known Parent DNA
What You'll Need to Provide
- Child's raw DNA file — Your DNA test results file
- Known parent's raw DNA file — DNA test results from your mother or father
Both files should be from the same testing company for best results (23andMe, AncestryDNA, MyHeritage, FTDNA, 24Genetics, ADNTRO…)
Your results are analyzed by Claude, Anthropic's AI model, which provides a personalized narrative explaining what the reconstructed second parent profile reveals about their ancestry, historical origins, and population heritage — giving your untested parent a genetic identity.
What's Included — 15 Analyses in One Report
Every report covers your estimated parent's ancestry at every depth — from 10,000-year-old migrations to modern population matches — with AI-written interpretation for each section.
