I am helping a friend with his Gedmatch match list.
This friend took a full-sequence mtDNA test at FTDNA and his mtDNA haplogroup is K1a-T195C!
He tested his maternal grandmother's autosomal DNA - she, of course, has the same mtDNA as he does - and uploaded her DNA to Gedmatch. One of his grandmother's autosomal matches included his full-sequence mtDNA haplogroup and it's K1a4a1a-T195C!.
I know a little about mtDNA, but I can't tell how close these are. I guess what I'm asking is - should I be looking for an autosomal DNA connection in the direct female line for these two OR are these subclades extremely different?
They're not matches at FTDNA.
Thank you!
