Looking for a MyTrueAncestry alternative? What people actually want from one — individual ancient matches, published statistics, one-time pricing — and which services deliver each, honestly compared.
How to run an ancient-DNA ancestry analysis from a whole-genome sequencing VCF — tellmeGen, Dante Labs, Nebula and similar — what happens to the file at upload, why it is converted to the panel's markers, and what changes versus a chip export.
What it means to share a stretch of DNA with a person who died thousands of years ago, why such matches are identity by state rather than identity by descent, what the centimorgan figures mean, and why a shared segment is never proof of descent.
