23 and me vs Ancestry DNA – The Roots of Each DNA Company
Just like with your ancestry, the beginnings of a company can speak volumes about its current status and founding principles. While both 23andMe and AncestryDNA offer similar DNA testing services, their roots are very different and their services have been tailored accordingly.
History of The 23andMe Company
A privately held genomics and biotechnology company, 23andMe is based out of Sunnyvale, California. It was founded originally as a genetic testing company in 2006 by Linda Avey, Anne Wojcicki, and Paul Cusenza.
The company has always prioritized genetic health testing and was founded with personal DNA testing services as a primary objective. Because of this, 23andMe now offers customers both ancestry-related DNA services as well as family tree and ethnicity services. This was the first mainstream DNA testing company to offer autosomal DNA testing services for ancestry and lineage tracing. In 2008, their direct-to-consumer (DTC) saliva testing business was named “Best Invention of the Year” by Time magazine.
Today, 23andMe is objectively the best DNA testing service available for predicting genetic health risks and has also been cited as one of the most accurate DNA testing services available to the general public. They offer autosomal, Y-DNA, and mtDNA testing services, and have a database of around 10 million samples.
History of AncestryDNA
Ancestry.com was founded by Brigham Young University graduates, Paul Brent Allen and Dan Taggart, in the early 1990s. A privately held company based out of Lehi, Utah. Ancestry.com began an information-sharing company called Infobase. This company grew to become Ancestry.com and later launched AncestryDNA, a subsidiary of Ancestry.com, offering a direct-to-consumer genealogical DNA testing service to the public.
AncestryDNA provides DNA analysis through saliva samples. They utilize a sequence of algorithms to infer family relationships with other AncestryDNA users called “ethnicity estimation.” While the company once offered mitochondrial and Y-DNA testing, those tests were discontinued in 2014. Today, AncestryDNA uses autosomal DNA testing and has a database of around 16 million completed DNA test samples.
Overview of DNA Testing Service
DNA testing involves the process of collecting a genetic material sample, processing that sample, and comparing it to other samples based on the information gathered. There are three main kinds of DNA tests on the market today: autosomal, y-chromosome (Y-DNA), and mitochondrial (mtDNA).
Autosomal DNA tests are used to trace ancestry through autosomal chromosome similarities. These tests are not gender-specific and so they can be used by either male or female participants; since everyone has autosomal chromosomes, these tests are equally effective for both genders. Everyone has autosomal chromosomes in their genetic makeup.
Your autosomal chromosomes contain segments of DNA that are shared by every relative you have. Thus, autosomal testing is an effective way to find any unknown biological family matches, trace your ancestry, outline your family tree, and more. Autosomal DNA tests can not give you information about your haplogroup, (a genetic population group of people who share a common ancestor) but they can give you information about many other genetic traits. Large autosomal comparison databases exist, making autosomal testing more accurate than ever before.
Mitochondrial DNA tests (mtDNA) are used to trace your maternal line. This is the ancestral line of a mother. Mitochondria are passed from mothers to their children. Everyone has mitochondria, so mtDNA tests can be used by both men and women. Mitochondrial testing helps you discover your mtDNA haplogroup. The mtDNA haplogroup is the group of people that makes up your matrilineage (lineage on your mother’s side).
Y-DNA tests identify the Y-chromosomes that are passed from father to son. As such, they can only be taken by male individuals. That being said, if a female wishes to learn about her patriarchal lineage, she could potentially have a male relative take a Y-DNA test on her behalf. These tests identify the male Y-chromosome haplogroup. This is the ancient group of individuals who make up a person’s patrilineage ancestors. Y-DNA tests can not trace females (nor their male ancestors) from whom a male descends.
How the DNA Testing Process Works
Direct to home DNA tests are very simple to take. You will receive a testing kit with instructions that will guide you in taking a DNA sample, usually a spit sample. You will then send back your saliva sample and have it tested by the company that you’ve ordered your test kit. This sample will be broken down through mtDNA, Y-DNA, or autosomal DNA testing.
The DNA data gathered from your sample will then be run through a large DNA database (DNA reference populations). These reference panels usually contain ten thousand other DNA samples. Using algorithms, the DNA testing center will be able to identify patterns and similarities between your DNA sample and other DNA samples. The results from this testing process will then be made available to you, usually through an online platform.
By using the online platforms and search engines available through the company of your choice, you’ll be able to discover information about your health traits, family tree, biological living relatives, and more.
Some companies allow you to upload raw data for an even more exhaustive research experience. Other companies (like 23andMe) offer chromosome browsers or close biological relative matching services. You may also have access to geological ancestry maps that can show you where your ancestors have migrated from over the centuries (migration patterns).
Keep in mind that different DNA testing companies offer users an array of platforms and break down genealogical and genetic health information in various ways. This is one reason that it’s important to use a DNA testing service that will correspond well with the information you’re looking to discern.
23andMe vs Ancestry DNA Results
Now that we’ve gone over some of the finer points of DNA testing, let’s take a look at how 23andMe and AncestryDNA compare side-by-side.
• DNA Testing and Sample Process
Both 23andMe and AncestryDNA use saliva samples to gather genetic information. Both companies also offer a direct to home DNA testing kit. You simply gather your sample and mail it back to the company for analysis.
DNA Ancestry Testing
AncestryDNA offers a saliva test that can be done from home as well. The test kit comes in the mail after you order it online. You will receive a kit, saliva collection tube, and prepaid return packaging. This kit requires more saliva than some other kits. Your sample is then processed by AncestryDNA at a lab and your test results will be viewable on the AncestryDNA website.
23andMe DNA Test
The 23andMe test kit process is pretty simple and the test kits are comparatively easy to use. You’ll order the DNA test kit of your choice online, and it will usually arrive within 3-5 business days. Express shipping is also available. You’ll then follow the instructions in your test kit. This sample process involves spitting into a test tube and labeling it. You’ll then mail your test kit back to the 23andMe lab using an included prepaid package. In 5-6 weeks, you will receive an email letting you know that your test results are available online in your account.
• 23andMe vs AncestryDNA for Ethnicity Estimation and Ancestry Test
Many DNA companies offer a percentage breakdown of genetics by ethnic region. The world is split into regions and a DNA test can tell you the percentage of DNA inherited from each area. 23andMe offers this in the form of a Geographic Ancestry Analysis while AncestryDNA gives you an Ethnicity Estimate. Both companies offer easy-to-read DNA results with visual aids and resources for further ethnic discovery.
23andme DNA Test Review
The Ancestry Composition report from 23andMe shows your DNA percentage from 45 populations spread across 1500 ethnic regions. They compare your genome to those of over 14,000 people with documented ancestry. Then, you’ll get what’s called Chromosome Painting which easily displays which regions your ancestors have originated from. Since 23andMe also offers haplogroup which shows your ancestors back 1,000 years or more. Also, you have access to your Neanderthal Ancestry which shows your Neanderthal genetic percentage. To get accurate DNA results, they use an Ancestry Composition algorithm which comprises five distinct steps:
1. Phasing – measures a set of genotypes
2. Window Classification – segmenting them into consecutive windows
3. Smoothing – classifies each window of your genome independently
4. Re-calibration – corrects for systematic bias
5. Aggregation & Reporting – summarizes the DNA results and displays them in a Chromosome Painting
This process gives you an extremely accurate ethnic picture. 23andMe has one of the most accurate ethnicity estimation systems due to its extensive database and ability to conduct mtDNA, Y-DNA, and autosomal DNA testing. To learn more about their testing and validation process, you can visit their online user guide. You can also learn more about the populations and regions used by 23andMe for reference by visiting this page.
Ancestry DNA Kit Review
AncestryDNA offers DNA ethnicity estimation from 1000+ ethnic regions for an accurate ethnicity estimate they can provide information on ethnicity estimation from centuries back. They divide ethnic regions by identifying hundreds of thousands of positions, or markers, in your DNA to build a panel of reference. These identifiers can help you determine your ethnicity and also possibly allow you to map historical migratory patterns.
AncestryDNA has a library of deep historical knowledge that can give you a comprehensive picture of what your ancestors may have been doing over the centuries. They present DNA data through a visual ethnicity chart. If your ethnic data is comprehensive, they will also create an interactive map with historical context so you can view migratory patterns in-depth.

• DNA Matches, Family History, and DNA Relatives
Both companies also offer DNA relative matches. However, their close relative criteria for identifying matches are not the same. The DNA matches you’ll get from AncestryDNA are generally more accurate than the ones you may receive from 23andMe.
Ancestry DNA Test
AncestryDNA tends to yield more DNA matches for its users, but this is because their criteria are 6cMs per segment and also their database is bigger.
23andMe DNA Test
They offer better criteria for matching segments of DNA, at 9 cMs and at least 700 SNPs.
• Health DNA Testing: Ancestry DNA vs 23 and Me
A DNA health test can help you determine a wealth of information about genetic traits and potential hereditary health issues. With these tests, you can identify carrier status (how likely you are to pass on certain genes to your children), receive wellness reports (find out which genetic markers may cause you issues), access a health predisposition report (find out which diseases you are genetically predisposed to getting), a genetic traits report (learn about your unique genetic traits), and more. Both companies offer health testing, though 23andMe has a better overall test with more reports and that tends to yield more information.
23andMe Health DNA Test
The Health test offered by 23andMe is one of the most accurate and comprehensive health test options available through home DNA testing. 23andMe health tests offer users access to more health and disease information than almost any other DNA testing company.
