Coming Soon: Y-DNA Haplogroups for Family Finder

[ArmandoR1b]

Here's something from Katy Rowe of Family Tree DNA, updated 29 August 2023, that indicates what kind of resolution we can expect from these FF Y-DNA haplogroups:

This means you’ll only receive a partial haplogroup from an autosomal test. Most customers can expect this haplogroup to have originated in the Metal Age (about 10,000 years ago). Comparatively, a predicted, broad haplogroup from a Y-STR test like the Y-37 or Y-111 will typically have originated in the Stone Age (about 100,000 years ago), and a haplogroup from the Big Y-700 will typically have originated in the Middle Ages or in the Modern Age (about 1,000 to 500 years ago)—within genealogical times.

Introducing Y-DNA Haplogroups for Family Finder Customers

That is because the chips used are either the OmniExpress or the GSA or similar. 

FTDNA and MyHeritage originally had the OmniExpress. FTDNA and MyHeritage went to the GSA chip in March 2019.
23andme v3 and v4 used OmniExpress. 23andme v5 uses GSA since August 2017.
AncestryDNA v2 still uses OmniExpress as far as I can tell.

Although each company can decide to have certain positions of the Y-DNA to not be tested or reported they are still limited by what the chip is capable of and none of the companies placed a high importance of the Y-DNA results. Every single person tested by a specific chip is tested for all of the same positions are reported in everyone's raw data. Due to this the number of positions each chip tested can be seen in the raw data for 23andme, Ancestry and MyHeritage customers.

23andme v3 and v4 OmniExpress tested less than 2185 Y-DNA positions.
23andme v5 tested less than 3397 Y-DNA positions.

AncestryDNA v2 Ominexpress tested less than 1745 positions.

The Myheritage files that I have tested less than 3496 positions. They must be from a 2019 GSA chip.

Based on the above results the reports from the FTDNA GSA chip will have something close to what MyHeritage and 23andme v5 has and the FTDNA Omniexpress will have close to what the 23andme v4 had.

Anyone with transfers from the other companies will get close to what can be seen with Yseq Cladefinder at https://cladefinder.yseq.net/ with the small exceptions of false negatives and false positives hopefully being ignored.

You can see what is reported in the 23andme v5 files at https://docs.google.com/spreadsheets/d/1...ue&sd=true The 23andme v4 positions that are tested can be seen at https://docs.google.com/spreadsheets/d/1...ue&sd=true

Let me say that if FTDNA follows through with it then it will be wonderful since people without Y-DNA tests and those with Y-DNA tests that haven't had SNP testing will have their haplogroup and FF and/or Y-DNA matches will be able to see if they at least share a similar haplogroup even if not as detailed as those of us with Big-Y testing would like it to be. For instance, L21 and U152 were tested successfully by both OmniExpress and GSA. So anyone that has Y-DNA STR markers that make them seem to be positive for one of those two but are actually negative for both L21 and U152 are now going to be very possibly DF27. Especially so if tested by GSA and negative for DF99.

I hope that FTDNA reports all positive and negative results so that customers can see what they are negative for apart for what they are positive for.
