FTDNA vrs 23andMe

Strangest thing, my friend tested with FTDNA and 23andMe

His Y Haplo with FTDNA is R1b1a2

23andMe has him as: R1b1b2a1a2f*

Anyone know how that could happen?

Thanks

Yes, different version of the Y-DNA tree being used.

R1b1b2 was renamed to R1b1a2 last year. 23andMe hasn't started using the new name yet.

I think it's because of utdated ISOGG trees. Both companies use ISOGG trees that are out of date, but 23andMe uses a really old one from before a lot of revisions were made. R1b1a2 used to be R1b1b2. If you look at the current tree:
http://www.isogg.org/tree/ISOGG_HapgrpR.html
You'll see there isn't even anything called R1b1b2 anymore.

This is exactly why people prefer the short version, like R-L21.

As others have noted, the nomenclature was changed (last spring), but FTDNA has not formally published it.

Your friend can go to Ancestry Labs / Haplogroup Tree Mutation Mapper and look for his most derived SNP. It would presumably be rs11799226 (also known as L21), where he would have a G instead of the ancestral A. Then go to the ISOGG tree http://isogg.org/tree and look up L21. The haplogroup in the ISOGG tree would be R1b1a2a1a1b4, but the more stable way of identifying the haplogroup would be R-L21.

There is an L21 project at FTDNA, which may accept 23andMe results if you write to the administrator.

My son had the same situation, and I sent the administrator the results of his haplogroup tree mutations from 23 and Me labs and he was accepted into the L-21 project.

In addition to what has already been noted 23andme does a deeper "initial" test than FTDNA. To get the same results at FTDNA as you did at 23andme you need to pay another fee to do a deep clade. However there are a number of subclades now under L21 which 23andme will not catch.
