I have been not done much with mtDNA, focussing more on atDNA and Y-DNA. As a result, I have just noticed (though we tested several years ago), that my mother and I do not appear on one another’s match list at FTDNA. However, our list of top matches is identical, including the genetic distances from those matches. Is this just a technical error on the part of FTDNA? Heteroplasmy was suggested to me, but that wouldn’t be the case if our matches and genetic distances are the same, would it? Janis Walker Gilmore Pawleys Island, SC
