View Full Version : Why the BIG change in Geno 2.0+ European reference populations?

Still haven't been able to find an answer to this, and Geno/FTDNA have been unhelpful and seemingly clueless to answer this very basic question about their own regional population profiles in the new test.

The European reference populations in the "First Generation" of Geno 2.0 (https://genographic.nationalgeographic.com/reference-populations/) all reflected some degree of Mediterranean or Southwest Asian DNA. This was the genetic component of the Neolithic migration into Europe from peoples of the Near East reflected in modern Europeans.

The European reference populations of Geno 2.0+, however, completely lack any such admixtures (https://genographic.nationalgeographic.com/reference-populations-next-gen/). Gone. Poof. Abracadabra. Into thin air. With the occasional remotely conceivable exception of some "Southern Europe" or "Jewish Diaspora" admixtures, the actual Neolithic components are gone. The reference populations are now almost wholly "European". Why? Nat Geno has not explained this recalibration, and it's irking me.

The readjustment has not been minor, either, nor merely semantic. If you compare the respective populations in the two different tests (linked above), you'll see that even in cases of "Southern Europe" or "Jewish Diaspora", the actual percentage is FAR lower.

Thoughts? Inside info?
