GEDmatch X-Matches and Trees Now Available!

GEDmatch X-Matches and Trees Now Available!

I decided to check again with GEDmatch Genesis today to see if one-to-many X-chromosome matching has returned. I?m glad I did, because it has.

The ?One-To-Many Beta ? give it a try? tool now lets you see all of your X-chromosome matches in one place

It leads you to a new page on which you enter your kit number. I thought the interface was quite nice, especially compared to the old GEDmatch.

Enter your kit number, change the radio button to ?X,? and click ?Search.? Also shown are the columns that are available for resulting matches.

There?s already an autosomal one-to-many tool on the Genesis site that you may have previously used. If you?re just interested in checking out the beta version, feel free to leave the radio button on ?autosomal.? Otherwise, and for the purpose of this article, remember to change it to ?X.?

I left all of the parameters on the default settings. I may at some point relax the thresholds a little just to see what other matches are out there. However, doing so will make the matches less certain.

When you?re ready, click ?Search.? The results came up very quickly. Autosomal information was also shown for each match, which I thought was nice. These are the columns that were displayed.

Now that the kit numbers of X-DNA matches are known, these can be used for analysis in the One-to-One Autosomal DNA Comparison and One-to-one XDNA Comparison NEW tools. Gedmatch recommends this in order to be certain that ?any match is real.?

Note that one of the columns in the X-DNA One-to-Many Beta results was for a GED or WikiTree. This feature is working now as well. It looks like I?ll be using the beta version from now on!

Feel free to ask me about modeling & simulation, genetic genealogy, or genealogical research. And make sure to check out these ranges of shared DNA percentages or shared centiMorgans, which are the only published values that match peer-reviewed standard deviations. That model was also used to make a very accurate relationship prediction tool. Or, try a calculator that lets you find the amount of an ancestor?s DNA you have when combining multiple kits.
