A curious turn of events has placed my M-DNA and maternal autosomal test results entirely in conflict with one another.
My M-DNA haplogroup is h-64, and every hit or near hit is concentrated almost exclusively in the British Isles (especially Ireland) or Americans with Irish ancestors. Given that my lineage on my maternal line is historically Irish, this was not at all surprising whatsoever. Indeed, I have pretty good geneaological evidence into the early 19th century that my maternal line is Irish.
Then I went ahead and did an autosomal DNA test on my mother owing to the weird results I was getting on my own autosomal test. As it turns out, my maternal autosomal test has come back with...
Nothing Irish at all, nor German (which is my grandmother's father's side).
How can this be? On the mitochondrial side, I am seeing a ton of Irish, including one person who is almost certainly a distant cousin owing to her genetic difference of 0 at full M-DNA sequence. But the autosomal tests give -no credit- to this.
I've compared my kits to my mother's and father's autosomal kits and have come up as their son on both accounts. But then my breakdown on Family Tree doesn't even match the breakdown the genetics would imply:
Father: 73 British, 25% Westeran/Central Europe, 3% Scandinavia.
Mother: 51% Scandinavia, 21% Southern Europe, 10% Finland, 17% Jewish diaspora
Myself: 36.5 British, 12.5% CEntral Europe, 26.5% Scandinavia, 11.5% Southern Europe, 5% Finland, 9% Jewish dispora by my approximate calculations.
Actual results: According to FT: Scandinavian 32%, Western and Central Europe 25%, British isles 19%, Finland and Northern Siberia 5%, Southern Europe 4%, Jewish diaspora 14%.
I don't see how this makes sense at all.
So I am left very, very much confused. Is this reflective of the poor accuracy of autosomal tests? Or what could be going on here?
I am most concerned about the obvious contradiction between a maternal haplogroup that speaks to definitive Irish origins, but autosomal data that suggests no such links, and indeed, links to far flung places for which I have no geneaological connection that I know of.
