Common maternal ancestor but different haplogroups

[Emona]

Ann, thank you for your explanation.

[Anizio]

There is one important possibility to consider, and its the first thing that came to mind when I read

"A researcher has"

People make mistakes, especially lazy "professions" and uninformed amateurs.

I'd have someone else go over your genealogy information to confirm it is actually accurate and there is not an error where you have accidentally traced the line of someone with the same name at the same time in the same place...but who was a different person than your ancestor.

Agreed, thank you Anizio. I am new to this and need to balance enthusiasm with caution.

@ Ann, by way of keeping you in the picture, I checked with help desk about the backbone test. They responded 'A backbone test is a SNP test designed to determine your paternal haplogroup by examining your y chromosome. It is not related to your maternal haplogroup'.

I am waiting for my mother's results and will then consider doing more detailed MtDNA tests.

The mtDNA backbone test is not a stand-alone test, so the help desk may not be familiar with the concept. It's mentioned in this FAQ:

But if your mother's results are in progress, they should settle the issue.

Updated reply from help desk: "There is no backbone haplogroup test for mtDNA tests. All of our mtDNA tests will determine the backbone haplogroup of the tester. The Full Mitochondrial Sequence can determine the haplogroup designation or more detailed haplogroup as well."

I'll hold on for my mother's results.

Thanks again

Ann, my mother's test results classify her as Haplogroup K.

Family Tree DNA attribute the error to a technical bug: "I am writing to let you know that the issue with your and your mother's mitochondrial haplogroups was found to be a technical bug and has now been resolved. You both come from haplogroup K, and your mother's account shows your full mitochondrial subclade to the highest level of specificity (her sample has had more extensive mitochondrial testing than yours, which is how this was specified)."

Thank you for your interest.

Anizio, my mother's test results which I received a few days ago classify her as Haplogroup K.

Thanks for the follow-up. All is well now.

I got that totally wrong then. I'm glad it has been resolved.
