View Full Version : J1 - Confused by my maternal haplogroup

Hi,

I rencently took a 23andme test and it taught me that my maternal haplogroup is J1:
42926

I was a little bit confused by it because as you can see 23andme associates J1 and the Vikings. The thing is, I know for sure that my grandmother on my mother's side is Basque. This was confirmed by my Living DNA results:
42927

So I did some research and came across this video in French: https://www.youtube.com/watch?v=5xGX0bx9xDI
I didn't know it, but according to this video there was indeed some relationship between the Vikings and the Basques.

So my question is: Is this the reason why my maternal haplogroup is J1? Or am I on the wrong track?
I'm pretty new to all this, so if you have any information on J1 I would love to hear it.

Here's some additional results:
42929 42930

Thank you.

Understand that J1 in of itself is really really old. At some point J1 branches off into other haplogroups downstream of J1, so that is likely where certain ethnicities are associated with the haplogroup.

Is your maternal haplogroup listed as "just" J1 on 23andMe? No a, b, or c after that numeral?

The mtDNA J1 is one of the more widely distributed West Eurasian maternal haplogroups, pretty much from the Middle East to Ireland, so you definitely can't associate it with any particular historical culture like early Middle Age Scandinavians or Celts unless you can narrow down the specific subclades.

Even then mtDNA is far more evenly distributed across geographic regions than Y-haplogroups due to socio-historical reasons...

Here's the constatly growing Yfull Mtree (https://yfull.com/mtree/J/); in case you're interested in seeing just how widely distributed J1 is, I find it odd that 23andMe didn't specify your haplogroup beyond J1, I got assigned J1c2 when I got my results.

Maybe you belong to a relatively rare early splitting branch of J1.

23 and me gave me just J1 also. I had to use Morley or whatever the mtDNA predictor was to get J1c2p, although I don't know if that's accurate or not/

mtDNA sequences are very short compared to chromosomes, and finding your particular subclade is very straightforward. You can try opening your 23andMe raw data in a text editor and searching for the defining mutation of, say, J1c2, A -> G at position 188 yourself. Here is my file as an example.

I'd recommend the OP download their raw data and do the same. Really weird that 23andMe is so vague with these maternal haplogroups.

I am J1 too, with a maternal line that comes from western iberian peninsula. Best regards to all J1's.

23andme gives me J1c2, but I had tested before at FTDNA to get my full haplogroup. All of my European matches are from Sweden.
