Ancestry Composition Numbers by Segment at 23andme.com

Did you know 23andme now provides the segment data for its ancestry composition assignments? This is a pretty recent feature and might even be useful. Unlike the other companies, 23andme does its admixture (aka ancestry composition) in chunks. This may make it more accurate than the others but in any case it means that they can give us the segment numbers. Then we can compare those to our matches.

To get these numbers, first pull down the reports menu and click on ancestry. On the initial ancestry page click on Ancestry Composition or the > symbol next to your highest group. Both are marked with my red arrow below.

The next page, the ancestry composition page has the pretty chromosome picture with ancestries displayed where you can change the confidence level from speculative (50%) to conservative (90%). To get a CSV file of the segments you click on Scientific Details at the top or the bottom of this page.

Then scroll all the way to bottom of that next page until you see this. You can select your confidence level as well for your downloaded data.

More about DNA relatives at the new 23andme

It is so delightful that you can now easily view your past correspondence with a 23andme match! To do this go to DNA relatives, which defaults to the People section, and click on the person. This takes you to a one-to-one comparison page partially shown below.

Your most recent message will appear in a box in the right hand column and you can scroll back in that box to see previous messages, both sent and received. Not all my oldest messages are there and I am not sure why. I did find one from 2012 and all the ones since 2014 seem to be available.

Past correspondence - as always, the red arrow has been added by me

Past correspondence in the People view – as always, the red arrow has been added by me

I used to have to use the chrome add-on 23++ in order to search my inbox or outbox which took a long time with four years worth of messages to search. Sometimes it even crashed! This is much better.

More on the People view in DNA Relatives

Can’t find the person? You can use the search box on the right in the People view to find them, an improvement over the first roll-out of the new site. Note that the search in the DNA view works immediately as you type, no buttons to push, while the search in this People view requires you to press return. Annoying that they are different.

You can now download your aggregated results from the bottom of the People view page. Continue reading

The new 23andme transition is here!

Many months ago we were promised that the transition would come in August. Last week on July 15, several of my accounts got an email that it was coming in a few days. Today, twelve days later, two of the ten or so accounts I manage at 23andme got emails that they have actually transitioned to the new experience, mine and my dad’s.

This is particularly exciting for me as I can now try out the new automated triangulation tool (click for previous blog post on that) with Dad and my Norwegian 3rd cousin. You need to participate in open sharing to have access to this tool.

When I visited Norway last summer, kits in hand, my third cousin gave me his DNA, so of course he got the new 23andme. I did a blog post on the new experience with his kit and went into the details of how to do the things I was used to doing on the old site on the new site – comparing people, asking for shares, checking new relatives, and so on. In this post, I will try not to repeat myself but rather to report on how the transition worked for me.

If your kit has transitioned, when you log in you see a big green button that says Get started that you have to click, as in the image above.. Continue reading

A Triangulation Feature on the New 23andme

An exciting triangulation feature has just been released at 23andme. It is only for profiles that have transitioned to the new site and have selected open sharing (for now). The feature shows you the relatives you have in common with one other profile and whether or not they triangulate with the two of you.

To use this tool you go to Tools > DNA relatives > People and pick a DNA relative to look at. At the top of the comparison page there is a menu item “Relatives.” Click on it to skip down the page where you will see a display like this (names removed for privacy):

When there is a “Yes” in the right hand column, there is a DNA segment in common between the two people you are comparing and this third person thus you triangulate. A “No” means that although you each share DNA with this relative, there is no segment of DNA where all three of you match. Click on the Yes (or a No) to see the three of you compared in the chromosome browser.

Once in the chromosome browser, you can use the “Update View – Edit” to add more people to the comparison with the first person. This is the same chromosome browser that you get to from Tools > DNA relatives > DNA

Jason Lee has done a nice write up with more details on his DNA blog at Tumblr:

Sadly you cannot use this tool with relatives still on the old site, since they have not yet been able to opt in to “Open Sharing” yet.

Patience please with the new 23andme

A while back I did a blog post explaining how to navigate the new 23andme (click here to read that). A number of my complaints in that post are now fixed. Most importantly, the ability to search for people to compare on the DNA Relatives > DNA page is there plus a table view which gives the numbers.

I cannot agree with the genetic genealogists who are abandoning 23andme due to the problems with its change over to their new web site, as well as the perceived lack of response to genetic genealogists. 23andme never made a secret of the fact that they are in this to research the genetics of various medical conditions. That is fine with me, as my extended family has many medical issues to look into, most, thankfully quite minor. They did make some nice tools for genealogists to attract more users into their database, but we have never been their primary concern.

While I do recommend Ancestry.com DNA testing for most new testers, many of my cousins want the medical information and so are willing to pay the extra for 23andme. It also has the best ancestry composition of the big three.

Personally though, my main reason for being patient and staying with 23andme is that I have found so many Norwegian and Norwegian-American cousins there (over 30) while only one or two at the other companies. Maybe we Scandinavians just have more genetic health issues. I also like the ability to compare cousins to each other and look at the ancestry composition by chromosome (although that is currently gone on the new site).

While 23andme is changing over to their new system, those of us with kits still on the old system have struggled to contact and share with our new matches. Initially we could not send shares to new matches so had to message them and ask them to send us a share. Thankfully that is fixed.
