View Full Version : Geno 2.0 Next Generation does NOT test for Z295*

(Before I begin, just FYI: I appear in the FTDNA "DF27 and Subclades" group as kit no. 74838, in the R-Z295* unassigned/paragroup.)

It seems that Geno 2.0 Next Generation does not test for Z295. I took the "first generation" version of Geno 2.0, and tested positive for all DF27 SNPs down to Z295, but no further. Hence my belonging to the Z295* "paragroup".

Well, I just got back my Geno 2.0 Next Generation results, and they took me back up one level to Z220. I looked at the raw data, and they don't include Z295 as a tested SNP at all. (I'm sure they test downstream SNPs, but if I'm legitimately Z295*, I wouldn't have those anyway.)

So now I'm left with a lower-resolution yDNA result that the earlier Geno 2.0 test. Hmph. :\


P.S. - I should add: When I transferred my Next Gen data to FTDNA, it (re)assigned me to R-Z295, as expected.

This is why the FTDNA SNP packs are better. Geno 2.0 only tests about 13 SNPs downstream from Z295. The Z209 SNP pack tests about 76 SNPs downstream from Z295 and it tests Z295. The BigY test is even better than any of the SNP packs.

True, but that's not even really my point. What I mean is, Geno 2.0 did test for Z295. Geno 2.0+ does not test for it. So contrary to their recent advertising, they now seem to be testing fewer SNPs that are relevant to a large number of M343 men.

True, but that's not even really my point. I understand that, but we can learn from your experience and determine which options are better. In my previous post, although I wrote Geno 2.0, I was referring to Geno 2.0+.


What I mean is, Geno 2.0 did test for Z295. Geno 2.0+ does not test for it. So contrary to their recent advertising, they now seem to be testing fewer SNPs that are relevant to a large number of M343 men.They never advertised that everyone would have more SNPs tested that were relevant to them. Only that they tested more SNPs. There are 12,051 SNPs in the original Geno 2.0 test. There are about 13,630 SNPs, not counting redundant SNPs, in the Geno 2.0+ test. Counting the redundant SNPs in Geno 2.0+ there are 15,561 SNPs. In Geno 2.0 there are about 648 M343 SNPs. In Geno 2.0+ there are about 853 M343 SNPs counting the redundant SNPs and about 750 not counting redundant SNPs. So although it looks like they are testing fewer M343 SNPs they are actually testing more but that still isn't enough to be better than the FTDNA SNP packs.
