  • MTDNA Matches Timeframe

    I have about about 15 mtdna matches on full hvr1,hvr2 and full mtdna test and about four of them and a Distance of about 1. According to the Ftdna learning center this is supposed to be pretty close genetically. But on Elise Friedman’s webinar she says that’s only for exact matches.

    Any idea on the timeframes for matches on the full mtdna with steps of 1 or 2 or more?

    Thank you

    Somewhere on this site, maybe in the learning center or a webinar there was something that I think mentioned in last 550 years for exact mtDNA full sequence matches, and 1200 years for 1 step full sequence matches, I think. It has an exact mtDNA plus match in the last 700 years. It has also been mentioned in the past that mutations in mtDNA are very slow and don't occur often, so in general a 1 step mt Full sequence match could have a common ancestor in the past 1200 years (if that is the right number) or could be in last 300 years, if a recent mutation happened to either person.

      It depends on what mutations are being counted as steps, and it also depends on how many recent mutations there are in your maternal line. Matches with a genetic distance of 1 or 2 steps could share a common maternal between 1 to 1000 generations ago. You can refine that estimate by checking the age estimate of your subclade, counting how many extra mutations you have in addition to those that define your subclade, and comparing your results to your close matches.
