Here’s How AncestryDNA is Improving Autosomal Testing

AncestryDNA product image new_1f_screens2You may recall from our recent DNA discussion on the Genealogy Gems podcast (Episode 168) that Ancestry.com recently discontinued their mtDNA and YDNA tests (the two that trace our direct maternal and direct paternal lines) to focus on autosomal DNA (which delivers information about both your mother’s and your father’s side of your ancestral tree).

Well, recently I attended an all-day meeting hosted by Ancestry.com: a summit to talk about current trends and accomplishments at Ancestry DNA, and ideas about the future of DNA testing at Ancestry.com.

The meeting included a diverse group of Ancestry representatives, from CEO Tim Sullivan to members of the marketing, scientific, communications, and even computer science departments, as well as some of the top voices in genetic genealogy. It was an open and lively discussion, and I walked away with a few gems I want to share with you today.

More Powerful DNA Hints Coming

In AncestryDNA, the ‘shaky leaf” hints are meant to help you find a common ancestor between you and your DNA matches. The computer code behind the old hints was not very efficient. Lazy, in fact. It started at the bottom of your tree—and the bottom of your match’s tree—and slapped on a shaky leaf at the first sign of a shared common ancestor.

AncestryDNA shared hint

While this method worked for a large number of cases, it was leaving a lot of stones unturned. But the IT guys at Ancestry have beefed up the computer power, allowing them to cover a much greater distance through our trees and the trees of our matches before making a judgment about the best place to assign that shaky leaf.

The result? Better hints about how you and your match COULD be related. Remember, the leaf is still just a SUGGESTION on how you and your match might be related. It is not a crystal ball.

Did You Know?

  • Ancestry DOES store your DNA samples in a secure location.
  • Ancestry spent months designing their own DNA collection kit.
  • Ancestry was able to attract some of the brightest scientists in the field of population genetics because of YOU. You with your documented pedigree charts and your willingness to help move this science of discovering our ancestors forward.

Looking Ahead

There is no question that the genetic genealogy industry is rapidly advancing, and our discussion with Ancestry certainly didn’t disappoint. While I will be sharing with you in future posts about some of the exciting changes, I do want you to be ready for one that buy anxiety medication online uk will be coming online fairly soon.

It has to do with your matches. If you have been tested by AncestryDNA, you may have been initially excited, then nearly immediately overwhelmed, by the number of individuals listed in your match page, all claiming to have some kind of connection to you and your family tree.

All three major genetic genealogy testing companies (AncestryDNA, Family Tree DNA, and 23andMe) are using basically the same laboratory methods to glean information from your DNA. What differs is how they use that data to draw conclusions about your ethnic heritage and about your relationships to other individuals. As it turns out, AncestryDNA has been reporting far more individuals as your relatives than it should have.

Autosomal DNA AncestryYou can think of it like this: You have sent out tickets, in the form of your genetic code, to an exclusive party where you (of course!) are the star. However, you have lost the guest list and you are counting on the testing company to check the ticket of each guest before they enter your party to be sure they were really invited.

AncestryDNA was relatively new in the role of party bouncer, and in the interest of not turning away any VIP guests, they initially allowed guests into your party who had (gasp!) forged tickets!! But as AncestryDNA admits more guests, the experience it’s gained in party monitoring is starting to show.

You see, each of the forged tickets has some unique qualities that have started to send up red flags to the team of scientists at AncestryDNA. They are now in the process of carefully documenting what each forged ticket looks like and tossing those unwanted guests out on their ear.

The short of it: in the near future your match list at Ancestry will be much shorter. Which is good news to you, as it means only those invited genetic cousins will be around eating hors d’ oeuvres and ready to talk about your shared common ancestry.

Each testing company has its strengths and weaknesses. It was good to have a bit of insight into this one company and come to a greater understanding about why it is they do what they do. It is a great time to be in this young genetic genealogy industry, with so much room to grow and change. I will let you know when I find the next genetic gem.

FamilySearch and Ancestry: Billion Record Deal

Ancestry.com and FamilySearch International, the two largest online providers of genealogy data,  just announced an agreement that’s expected to put a billion more historical records from around the world within reach online.

1 Billion Records FamilySearch and Ancestry

FamilySearch and Ancestry: Billion Record Deal

A billion is a LOT of records. If you wanted to count to a billion, it would take you 95 years.

According to an Ancestry.com press release, the organizations will partner “with the archive community over the next five years to digitize, index and publish these records from the FamilySearch vault.”

“The access to the global collection of records marks a major investment in international content as Ancestry.com continues to invest in expanding family history interest in its current markets and worldwide,” continues the release. “Ancestry.com expects to invest more than $60 million over the next five years in the project alongside thousands of hours of volunteer efforts facilitated by FamilySearch.”

This kind of collaboration (rather than competition) between these two enormous organizations will likely mean fabulous fruits for the genealogist. I love that the emphasis is on worldwide records, too. Though people in certain international markets may be the ones using their records, the ancestors of those folks have come from all parts of the world. As always, stay tuned to Genealogy Gems to hear news like this and for updates as these records start becoming available.
