PF SNPs

[1798]

I have a new SNP, PF970. Does anyone know anything about it?

Just this.

I would be very skeptical of this SNP on the Geno 2.0 chip. Do a Google search for "PF970+ Family Tree DNA." The results show that FTDNA customers are showing a PF970+ result on the SNP page of various haplogroup projects.

This SNP has had a positive result in men from haplogroups C, I1, E1b1a8a, R1b-Z343 and R1b-M343. There may be other haplogroups where PF970 is showing up as positive, but I think the point has been made sufficiently by citing 5 different haplogroups that have a positive result.

Either the Geno 2.0 is generating false positive results for PF970 or the SNP is located in an unstable area of the y chromosome and probably isn't reliable to use for updating the haplotree. At least that's how it looks to me.

According to the Finch it's hg A

Huh? Take a look at the map. More samples are in England than anywhere else. It's likely the higher density is because more English / Americans (with English ancestry) tested and not a true representation of the frequency.

It looks like a hunter-gatherer SNP.

Shows up in my brother as well, and he is in an R1a1a haplogroup.

I've got it too. It showed up in my FTDNA Y-Group page.
