A few common things. Your file may cover too few mitochondrial positions to reach the branch you expected; a stray or miscalled variant can shift a call; and deep-time lineage often simply doesn’t line up with recent paper-trail genealogy, which covers only the last few centuries. If it still looks off, send your file to our team and we’ll take a look.
