Native Americans and Polynesians

[BalkanKiwi]

Hi all,

I've been doing general browsing of my GEDMatch matches, and came across something that may? be interesting. I have two matches that have a maternal haplogroup of B4’5 listed (siblings I assume). I’m not well versed in Native American genetics however from what I understand this is a common Native American haplogroup. I’ve seen these matches before and haven’t thought much of it. I assume most people would match a few who have some Native American DNA.

Out of curiosity, mainly due to my minor Polynesian ancestry, I thought I’d see if anyone else matches our kits. When looking at the chromosome segment matching, I matched 4 kits in the same place on chromosome 1, two of which are the above Native American kits.

To begin with, I checked out where I matched the Native American kits. As expected, our shared segment is mostly Atlantic, Baltic, West Asian etc. I noticed between 207M-208M, we share a small amount of Amerindian. I checked the other sibling and as expected, there it was.
I also checked the other two kits, and to my surprise I also match them in the same Native American spot.

These are the relevant autosomal results from the Eurogenes K13:

Match 1 – 12cM chromo match (Haplogroups not listed)
East_Asian 0.27
Amerindian 0.53
Oceanian 0.46

Match 2 – 11cM chromo match (Haplogroups not listed)
Siberian 0.93
Amerindian 0.69

Match 3 (Sibling?) - B4’5 – 10cM chromo match
East_Asian 0.99
Siberian 3.33
Amerindian 14.77

Match 4 (Sibling?) – B4’5 - 10cM chromo match
Siberian 3.73
Amerindian 13.16
Oceanian 0.56


Now I’m not saying I have Native American ancestry and that we share a common Native American ancestor, as that would be inappropriate and likely incorrect, however to those more versed in Native American genetics, is there a logical explanation for this?

Is it simply general shared ancestry in some way?

Hello, possible distant cousin. I'm B2, and B2f more specifically and it comes from B4’5. This group is believed to have originated in central Asia and many other groups descend from it, one of which is Polynesian, others are in China, Japan, etc...

Here three GEDmatch kits of people who are fully Native American:

M174237
M192137
M637791

They have similar GEDmatch results as Clovis Anzick-1 (F999919).

Three more people who are almost fully Native (a bit Euro-admixed):

M051413
M283662
M221108 - mostly Mayan

I'm guessing that the B4'5 is their results from only testing HVR. I see at least one such case for a man from Samoa.

The only DNA I know that links native Americans to the South Pacific is (OCA 2)
