Autosomal DNA testing comparison chart

Distinguishing 23andMe V2, V3, V4 chips

Can the dates the 23andMe was using its V3 chip be added to this chart, in the spot where it mentions that FTDNA accepts V3 uploads? The relevant dates appear to be roughtly Nov 2010 to Nov 2013.

I've now added the dates. FTDNA did provide further information about the transfers in their recent e-mail to admins: "There are a couple of ways to find out what chip was used for your test other than simply the timeframe. One is size; v3 chip files are about 7.83 MB where V2 and V4 chips are smaller. If you’re tech savvy, you can unzip the file and check chromosomes: Chromosome 1 for v3 starts at 82154 (rs4477212) where v4 starts at 734462 (rs12564807)and v2 starts with position 742429 (rs3094315)." I wonder if it might perhaps be appropriate to add this as a footnote. DebbieKennett (talk) 03:37, 28 October 2014 (MDT)

Database sizes

Ancestry CEO Tim Sullivan reported on Feb. 17, 2016 that "We have over 1.5 million DNA samples in our database" in the Q4 2015 Results - Earnings report.

Thanks for alerting us to this. I will contact Tim Janzen and see if wants to update the database sizes. He normally likes to update all three companies at once so he might want to try and get updates for 23andMe and FTDNA. DebbieKennett (talk) 14:36, 8 March 2016 (MST)

New number for Geno 2.0

Updated info for the Number of people in the database (Geno 2.0):

About 230,000 (Geno 2.0 and Geno 2.0 NextGeneration)

• Thanks Leah for the info. I've updated the page. DebbieKennett (talk) 14:43, 15 March 2016 (MDT)

width of chart

Is it possible to add a side-to-side scroll bar for the comparison chart? It's too wide for a laptop screen. At maximum window width, I can only see 23andMe, FTDNA, Ancestry, and part of the NatGeo column. To see MyHeritage, I have to move the browser window to the left (so that it's partly off-screen) and make the window wider. Of course, then, I can't see the left side of the table!

Someone else has raised this with us. It doesn't seem to affect everyone and is not browser dependent. I've asked Tom, our webmaster, to investigate.DebbieKennett (talk) 08:46, 8 July 2017 (EDT)

I fixed this. The issue is URL width always wins when there is no suitable break point. domain.org/this/that/here/index.html will not break to the next line. domain.org/this-that/here-iam/index.html will break at the hyphens in the URL. I removed the rest of the http:// in front of the company URLs, and the two links (one to a blog, the other a video) I made the URL use a description of the content not the URL itself.

LivingDNA

What do you think about adding LivingDNA to this autosamal comparison chart?

I think the idea was to add Living DNA to this chart once they introduce matching so that the test can be used for genetic genealogy. That should happen some time within the next four or five months.DebbieKennett (talk) 18:17, 23 October 2017 (EDT)

New AncestryDNA figures

AncestryDNA has hit 6 million tested: https://www.ancestry.com/corporate/about-ancestry/company-facts

AncestryDNA is at 7 million now

Nat Geo - Geno 2.0

The current chart defines it use for ...
Population Genetics Research
Personal Ancestry (Autosomal)
Personal Ancestry (Y-DNA)
Personal Ancestry (mtDNA)

However, some have confused Y-DNA as STR testing instead of Y-DNA SNP testing. The same for mtDNA.

I suggest that the section be modified by changing (Y-DNA) to (Y-DNA SNP) and (mtDNA) to (mtDNA SNP).

Many thanks. We are in fact planning to change the format of the chart and move Geno 2.0 to a different section as they don't do cousin matching. However, it will take a while for this to take effect but we'll bear this in mind. DebbieKennett (talk) 19:05, 20 January 2019 (EST)

FTDNA / MyHeritage new chips

Both FTDNA and MyHeritage have begun using new chips. Can the chart be updated to reflect this?

FTDNA uploads

FTDNA is now accepting 23andMe V5 uploads. It also allows transfers of MyHeritage tests

MyHeritage availability

MyHeritage is now available in France, Poland, and Alaska. However, per their T&C, "The DNA Services are currently not available to residents of the following locations: Israel, Iran, Libya, Sudan, Somalia, North Korea, Lebanon and Syria." See the DNA Services section at https://www.myheritage.com/terms-and-conditions

FTDNA's Chromosome Browser

When FTDNA updated their chromosome browser in late 2018, they expanded the number of people you can compare at one time to 7.

FTDNA new figures

FamilyTreeDNA How big is the database?

2.5 million DNA profiles The New York Times, Dec 22, 2019. https://www.nytimes.com/2019/12/22/science/dna-testing-kit-present.html

Ancestry and 23andme are reported with 15 millions and 10 millions. So FTDNA probably has a bit over 2.5 millions tests.

Also here: That company is FamilyTreeDNA, a direct-to-consumer genetic testing firm similar to Ancestry and 23andMe that has around 2.5 million DNA profiles in its database. Onezero.medium.com, March 11, 2020. https://onezero.medium.com/how-cops-are-using-your-dna-to-catch-criminals-fe27a1d69e85

Thanks for those links. The difficulty is that the links do not provide the breakdown of Family Finder, Y-DNA and mtDNA tests. However, Martin McDowell did an assessment based on FTDNA kit numbers which puts the FTDNA Family Finder database at approaching two million: https://ggi2013.blogspot.com/2020/02/how-big-is-familytreedna-database.html We're currently in the process of updating the content of this page to replace the Genographic Project with Living DNA. I will pass these links on to Tim Janzen for him to review.****

23andMe

Ownership should probably be updated for 23andMe. They went public on 14 June 2021 and are no longer privately held. Also, their current corporate FAQ (https://investors.23andme.com/static-files/ad9292c0-2c0a-4df1-ba3e-dea9b07f73f2) reports "13+ million genotyped customers"; the next full-year results should be reported at the end of May 2023.
