- How does Y-chromosome DNA (Y-DNA) haplogroup prediction work? www.familytreedna.com/learn/y-dna-testing/haplogroups-snps/prediction/
- What is tested with the SNP Assurance Program? www.familytreedna.com/learn/project-administration/gap-interpretation/snp-assurance-program-2/
Due to its low resolution, Y-DNA12 cannot be used anymore for anything but large population studies. Convergence is readily apparent.
I was not able to find the original FTDNA announcement about displaying only matches that are within one's major haplogroup (as predicted or determined by SNP testing). Maybe someone has archived it and could post the actual wording.
