23AndMe Tree

News about the new tree is starting to come out.

In order to utilize the new tree feature, you must enable Beta for your account, which you can find under your name in the Settings area.

Be sure to go to the dna-explained.com blog to see Roberta Estes’ thoughts on the tree.

Adoptees must think they’ve died and gone to the happy hereafter, because all other vendors’ tree support requires you to actually HAVE a tree of some description. Of course, adoptees and people seeking an unknown parent don’t have trees for their unknown parents.

The following was written by 23AndMe themselves.

“Your family tree is written in your DNA, and 23andMe researchers have developed an algorithm that can help you read it.

“Instead of relying on customers to painstakingly enter names and dates — or tracking down records — just to get started, 23andMe new Family Tree does it for you using your genetic connections and DNA Relatives.

“With the click of a button, your genetic family tree is built automatically by an algorithm that predicts relationships based the DNA shared between you and your DNA Relatives. The size of your family tree depends on how many connections and DNA Relatives you have close relationships with in the 23andMe database. Participating in 23andMe’s DNA Relatives tool helps improve the experience. Customers will also be able to add names of relatives, or ancestors, to the family tree whether or not those individuals are on 23andMe. As the 23andMe database grows, customers may see their trees expand.

“We created this new feature because we heard from customers who want to understand their recent family history, but don’t want the hassle of building a traditional family tree from scratch. The team is also working on additional functionality, such as the ability to edit your predicted relationships, which is expected to roll out in the coming weeks. 23andMe’s Family Tree offers a simple friction-free option, and a beautiful way to visualize how you connect with DNA Relatives.”

New 23AndMe Predicted Tree

23AndMe is at it again! They are experimenting with a Tree built from your DNA matches! They are calling it your “predicted tree”. It is similar in purpose to Ancestry’s Thrulines and MyHeritage’s Theory of Family Relativity but it is using those 23AndMe cousins who have been really hard to trace.

I just discovered it today… it hasn’t been discussed yet anywhere and doesn’t even have a real name yet.

Finding this new tool is easy in the IOS App, just move down the home page to where the icon to the tree appears, and click on it.

In the PC site, go to the “Ancestry” section, then go all the way to the bottom of the page and find “Family Tree Beta” in the right of the footer section. Or go to the “Family” section and pick the “Family Tree Beta”.

You should really check this out. It is great. This is the first DNA only tree I have seen. It only goes back 5 generations, and perhaps it limits display to those matching greater than X centimorgans.  We’ll find out details in the future.  Meanwhile,  I figure that the more people who use it, the more likely they are to keep it! Here is a snip from my predicted tree. Note the two cousins names next to my picture:

Perhaps we can explore this new tool at the first meeting of the Genealogy & DNA Discussion Group 🙂

number of SNPs tested by chip

I am testing the process of creating a Post here via Email. If it works well, perhaps we can get other folks to create postings too. This particular post might come or go rather quickly, so be-aware!

On a more serious note, I am going to create a table showing the number of SNPs tested by chip for the different testing companies. I was hoping to find what I wanted online somewhere, but alas, I will create one myself using these links.

23andMe Maps

Honestly, I don’t hang out in the DNA testing sites as much as you might think. And when I do go to a site, I usually have a purpose, so I don’t try out new stuff that often. 23andMe has a new feature I just noticed a couple of days ago called MAPS. It is located in the DNA Relatives section, under either Ancestry or Family & Friends. Today it is highlighted in bright orange. I wasn’t expecting much as Maps at other sites are usually pretty boring. But I needed to try it.

When you see a match, you can click on it and it shows you the person’s name, relationship and city. Clicking on that display links to the DNA Comparison section with you and that person compared, which includes the segment comparison. It is slick indeed.

The MAP covers the world, wherever 23andMe has customers. I saw a few matches in Northern Europe, cool. Perhaps they can help me with some brick walls.

I decided to look around my local area, the Monterey County section, where much to my amazement, there are two 4th cousins showing! I was flabbergasted. Neither surname is known to me. But they are real 23andMe customers who are related to me somehow and they live just down the road. I am going to have to contact them.

Of course, my first email has to be gentle. I don’t want them to think I am stalking them! I need to locate some of those “recommended introductory” email examples that are floating around. I might even invite them to come to the FHC to meet me!

Then I stopped to think: “Could they see me all this time and have never contacted me?” Humm. Remember, I don’t know how long the MAP feature has been around. That thought led me to wonder about my own personal Profile in 23andMe. The current City was showing for people in my MAP, so that meant the Profile had to allow current location to be visible to everyone. Humm again. I had setup my profile so long ago that I couldn’t remember what it said. So I decided to check it, because I want my relatives to be able to find me!

I went to Settings under my name, clicked Edit under Personal Information and found Current Residence. It was blank! Darn…. I quickly changed it and am now waiting for someone to find me!

My recommendation to you, if you are a 23andMe customer, is to try the MAP. Look around, look where you were born, look where you live now, etc.. Then, if you like what you see, check your Profile too. Make sure you have Sharing allowed and Current Residence filled in. And then send your own “recommended introductory” emails.

And if you get an introductory email from a cousin, answer it!

23andMe Upgrade Policy Coming?

I tested my DNA at 23andMe in February 2010 on what was called their “chip 2”. Time marches on and 23andMe has developed new chips and new Wellness reports. They are on “chip 5” now. Some of these reports are not available for people who tested early because the SNPs used in the new reports were not included on the older chips.

A couple of weeks ago, I sent a note to the 23andMe Helpdesk asking about an upgrade policy wherein I could retest AND keep all of my ancestry matches I have collected over the years and not have to respond again to all of those health questionnaires.

The Customer Care team responded within a few days with some optimistic news. I don’t think it is wrong of me to share part of their response with you, especially since they did not say it was a secret. This is the salient part:

“Customers genotyped on our latest genotyping chip are eligible for the reports. Upgrades are unavailable at this time. We are currently working on an upgrade policy for our customers and would encourage you to wait for this policy to be finalized. The upgrade policy will allow you to be genotyped on our most up-to-date chip at a discounted rate. More information about upgrades will be available in the coming months.”

I am excited about what this “upgrade policy” will include. They did not specifically say my matches would be retained, but the very idea that they are thinking about it sounds hopeful. “Willing to wait, I am.”
