X-DNA Inheritance Charts

A few years ago The Genetic Genealogist Blaine Bettinger posted several versions of X‑DNA inheritance charts. Colored blocks on the charts indicate which ancestors might contribute segments to a person's X chromosome(s). The percentage of X‑DNA that each ancestor might contribute was shown in one of the later charts.1 Blaine explains X‑DNA inheritance in those posts as well as providing the charts.

I formatted this information into a Microsoft Word table so I can type the names of the ancestors of a person who has tested for use in X‑DNA analysis.


I don't like to use handwritten charts when I can create a printed version.

With Blaine's permission I have attached a Creative Commons license2 and am linking several different electronic formats of the documents for use in compliance with the Creative Commons license.

I hope these charts prove useful to the genetic genealogy community. If anyone has problems or sees errors in the charts please let me know so they can be corrected.

  2. Hi Debbie:

    I like to be able to have my ancestors names printed too, so thanks for making these charts available. I've tweaked your charts slightly and put Generations 1-3 running sideways with much slimmer columns, which allows the columns for Generations 4 through 7 to be wider, to accommodate the full names of my ancestors all on a single page. I've added Ahnentafel numbers too as superscripts). See http://www.genealogyjunkie.net/x-inheritance-charts.html.

    1. Very useful modifications to the charts, Sue. I didn't see a link to download a copy of your modifications, but anyone can modify the copies I link to and incorporate your changes due to the Creative Commons license. I'm still trying to catch up from the Texas State GS conference and the Family Tree DNA conference, but can try to update my links when new versions of doc, pdf, etc. files have been created with your tweaks. Thanks for letting us know.

  3. Hi Debbie:

    Templates with my tweaks are now available for download for Pedigree Charts and Male and Female X-DNA Inheritance Charts at http://www.genealogyjunkie.net/downloads.html. I'll aim to keep each of these as fixed links from a public Dropbox folder.

  5. Shirese, I'm glad these are useful and I love Sue's mods. A great thing about putting something out with a Creative Commons license allowing derivatives is that many people can improve on the original and share with the rest of us.

  6. I really like this vertical chart--much easier to understand and to use. Thank you!

  7. I'm glad the vertical charts are useful to others besides myself, Kay. The fan charts are pretty, but I find them harder to read and use.
