What is the deal with X matches at FTDNA? (i am female) Will researching my X matches at FTDNA help me find paternal ancestors? @Genetic Genealogy Research
I don't really know. Here is the FamilySearch Help information:
Probably not helpful.
I went on my FamilyTreeDNA.com. I don't understand it. Anyway, I took the autosomal test as I knew who my mDNA and yDNA were.
So I only get general matches to cousins. Same with my ancestry test.
There must be someone here who knows about DNA.
To answer you question directly - maybe. There is a particular pattern of whom you can inherit X-DNA from (all maternal), and the amount needs to be significant enough to be useful - just like atDNA. X-DNA matches are more difficult to use, but can be useful in combination with autosomal DNA (atDNA), and can help you narrow down which line the test taker might be from. Here is the official ISOGG article (https://isogg.org/wiki/X-chromosome_testing), and one of the other more layperson articles is referenced: (https://www.legacytree.com/blog/x-dna-autosomal-dna-inheritance-paths. And as part of another article, here's a chart of X-DNA inheritance: https://thegeneticgenealogist.com/2008/12/21/unlocking-the-genealogical-secrets-of-the-x-chromosome.
Ty @Anitra Whittle 😊 I get so confused with trying to use FTDNA also.. and gedmatch, living.dna, and pretty much all the rest of them 🤣 another user here has been super helpful in helping me narrow down the possible birth family/ancestors of my adopted paternal grandparents ... I just get so lost in trying to make sense of it all 🤣
Ty @Fearer Mark i will check that out! For some reason I thought x dna was a paternal thing? I’m searching for my fathers adopted parents (his mother and father both were adopted) bio family and was hoping the xdna matches at FTDNA would help me sort some of this stuff out. Ty for the info! I’ll let you know how I make out:)
