I recently got the results for my grandpa's uncle, which is haplogroup b2(jameslitwick's tool further refines it to b2r), and so far only one one match in hrv1 level showed up and they were b4'5 instead. I thought b2 was common, so why does my great grand uncle only have one mtdna match

No announcement yet.
how many of you have little or no mtdna matches

I personally do not see much value in the MtDNA test for genealogical purposes.

I have several exact or 0 step matches after doing a FMS for the mtDNA test. Everyone, but 1, of these matches have also done the FF test, which we don't match on. The one exact match that didn't take the FF test has been in contact with me and we can not come up with a likely maternal link, due to wrong names and locations for matching. But I was told to sort of expect this by my haplogroup administrator.
At the lower levels of the mtDNA test I have a number of matches but as they have done the FMS test, they've disappeared. It can be an exact step match at HRV1 and mean nothing when it comes to your actual mtDNA at a deeper test.
Sort of the same thing with the Y-DNA test. My brother has a page of exact or 0 step matches at 12 markers that totally disappear at 67 markers.Last edited by keigh; 24 March 2017, 10:59 AM.

Having done FMS, my mtDna results are as follows:
O step - 17 matches. 10 of these have done FF, but no atDna match.
1 step - 13 matches
2 step - 6 matches
3 step - 1 match
I did FMS testing 6 years ago, and I get a few new matches each year.
I am U3a1b.Last edited by Biblioteque; 24 March 2017, 03:42 PM.

mtDNA and Y-DNA can be very useful when it comes to confirming possible maternal or paternal line matches. If you can get someone you think might be a match to you along those lines, then doing the full tests can be very helpful.
However, when it comes to just taking the test simply on the hope of discovering a way to get over or through a brick wall, the tests just aren't that valuable for current genealogy. This is especially true with the mtDNA since maternal lines depending on the culture, may change with each generation. The Y-DNA can be more surname linked.

In order for someone to appear as a match at that level of testing, it has to be an exact match. If you have one uncommon mutation and have only taken the basic test, then there's a good chance that you won't see any matches, since no one matches your uncommon mutation.
Matches at the full sequence level of mtDNA testing, which includes the coding region, don't have to be exact. Anyone who's taken the full sequence mtDNA test will be shown matches who differ with them on three or less locations.

Thank you MMaddi,
No, I did take the full sequence mtdna test and I have absolutely zero matches, which seems very strange to me. This test was taken over a year ago...
I suspect I must be an alienIs it possible that I have such an uncommon subclade?

Originally posted by MMaddi View PostFor you to have taken the full sequence test and have no matches at all, it must mean that you have at least 4 uncommon mutations. The up side of that is that there's a good chance that anyone who differs with you on only one or two mutations shares a common ancestor with you in the last few hundred years.Last edited by crossover; 24 March 2017, 11:04 PM.

Curious as to how we can tell what is an uncommon mutation. I also have never had a match, having taken the full sequence test several years ago. I always figured it was because my maternal line comes from a small remote village in Switzerland.
