Best Free Ancestry DNA
You’ve had your Ancestry DNA tested with a genetic genealogy company (maybe even quite one). You’ve reviewed your ethnicity estimate and you’ve skilled your match list. Now, what does one have to do? How do you maximize your testing dollars to wring equally useful genealogical information out of your test(s)?
The solution could also be in tools at third-party websites—so, not the sites of companies offering the best DNA testing. Which offer you new ways to research your test results. This will lead you to revelations about your genealogy.
I’ll show you ways to use the simplest free third-party tools to research your autosomal DNA and make new genealogy connections.
AncestryDNA, 23andMe, MyHeritage DNA, and Family Tree DNA
Each of the main testing companies—23andMe, AncestryDNA, MyHeritage DNA, and Family Tree DNA—offers tools its customers can use to interpret their results. They provide additional capabilities and features. You won’t find provided by the testing companies, boosting what you’re ready to accomplish genealogically together with your DNA results.
For instance, the sole thanks of comparing raw DNA data from one company’s test to data from another company’s test is to possess both sets of knowledge uploaded to an equivalent third-party tool.
How and Why to Download data from AncestryDNA
Third-Party DNA Tools
These tools can assist you to visualize your DNA in several ways. You’ll produce spreadsheets that put the info at your fingertips and show you insightful patterns and trends in your DNA.
They will assist you to use a posh research technique referred to as “triangulation,”. During which you employ data from two different sources—in this case, two of your matches’ genetic information—to draw conclusions from a few third, unknown source (i.e., a shared mystery ancestor).
Our guide will specialize in the 2 most ordinarily utilized third-party tools, hosted by GEDmatch and DNAGedcom. Let’s probe what each website offers.
Curtis Rogers and John Olson created the most popular third-party tool GEDmatch. This assists user can upload their raw DNA data and perform a spread of analyses. The location offers additional tools for paying users, but the free account is sufficient to start out.
Once you’ve got a profile, you’ll access the GEDmatch tool and upload a “kit,” or the data results from a test, for processing and inclusion within the GEDMatch database. You’ll be assigned variety for every kit you upload. Make certain to write this down where you won’t break it down.
DNA Q&A: GEDmatch
The most page of GEDmatch displays different information. Within the File Uploads panel, you’ll find links with step-by-step instructions for downloading data from each testing company and uploading the info to GEDmatch.
For others, you’ll be got to wait each day or two for your raw data to be processed. The most page gives you access to several free tools available at GEDmatch. The foremost important and most ordinarily used are indicated on the image below:
A. “One-to-many” matches: These compare the data of one kit to the data of each other kit within the GEDmatch database.
- One-to-one compare: This compares the atDNA data of one kit to the other kit to spot segments of atDNA shared between the kits above the sharing threshold. You’ll manually adjust the sharing threshold to be higher or less than the default 7 cMs.
- X one-to-one: This compares the X-chromosomal DNA data of one kit to the X-DNA data of 1 other kit so as to spot segments of X-DNA shared between the kits above the sharing threshold. Again, the default is 7 cMs, which you’ll adjust. X-DNA is on the X-chromosome.
Each man has an X chromosome, which his mother inherited. Two X chromosomes have each woman, one from each parent. This pattern can complicate the analysis of X-chromosomes. So you’ll want to consult resources like my aforementioned book The genealogy Guide to DNA & Genetic Genealogy. Therefore the International Society of Genetic Genealogy Wiki.
This process uses one of several different ethnicity calculators to perform an ethnicity analysis. You’ll view leads in various formats, including as percentages, during a chromosome browser, or as a chart, among others.
People that match one or both of two kits: This analysis uses two kit numbers to spot genetic cousins above a sharing threshold in three different categories:
1) Kits within the GEDmatch database that match both of the entered kit numbers; 2) Kits within the GEDmatch database that match only the primary of the 2 entered kit numbers, and 3) Kits within the GEDmatch database that match only the second of the 2 entered kit numbers. If you entered your kit number and your mother’s kit number, for instance, you’ll find 1) matches you both share; 2) people that match you but not your mom; and 3) people that match your mom but not you.
Are your parents related?: This determines whether a kit has any segments of atDNA that are equivalent from both parents. Meaning both copies of a chromosome have an equivalent DNA—and were inherited from an equivalent ancestor—at that location. this will occur if the oldsters are related.
Genetic genealogists curious about learning more about their atDNA test results should experiment with the tools at GEDmatch and keep checking back because the site continues to grow and develop new tools and functionality.
Rob Warthen launched DNAGedcom in February 2013 with tools allowing users to download important data files from 23andMe and Family Tree DNA. It also has tools for comparing GEDCOMs, performing ICW analysis, and triangulating DNA results.
Once you’ve created a free DNAGedcom account. You’ll perform analyses with data from each of the three testing companies, plus GEDmatch. You’ll download family tree DNA data from that company’s website by hovering over family tree DNA on the DNAGedcom main menu. Clicking Download family tree DNA Data, and entering your Kit number and genealogy DNA password.
Similarly, uploading data from GEDmatch is comparatively straightforward—simply hover over DNA-kits on the most page, then click Upload GEDmatch DNA Data (Beta). However, would require you to possess a paid subscriber account. For more on downloading and using the appliance, see DNAGedcom’s guide.
Once you’ve uploaded your data, you’ll have access to many tools, including:
Autosomal DNA Segment Analyzer
This tool uses GEDmatch data to get tables of data on your matches, DNA segments, and ICW matches. You can then triangulate matching segments between groups of three or more individuals. Although as explained within the Autosomal DNA Segment Analyzer quick guide page 61, this tool doesn’t provide “perfect triangulation.”
This downloadable Excel Tool creates a table that identifies possible triangulation groups with overlapping segments and your ICW status among your matches. This tool generates a table of overlap segments and ICW status between matches to identify possible triangulation groups. KWorks is that the online version of JWorks, and KWorks requires an equivalent of three components.
This tool compares genealogy information to spot shared ancestors. It can use GEDCOMs uploaded by the user, genealogy information downloaded from matches at AncestryDNA using the DNAGedcom Client, and genealogy information downloaded from matches at genealogy DNA using DNAGedcom’s Download genealogy DNA Data tool.
See DNAGedcom’s guide for more information about GWorks
Like GEDmatch, you’ll want to watch this and other third-party tools to remain AU courant changes.
While the analysis tools offered by DNA companies can sometimes be limited in their scope and utility, applications created by companies like GEDmatch and DNAGedcom can provide valuable information and therefore the ability to match your DNA to results from different testing companies. The new information and connections you uncover could be the key to unlocking a family mystery. A version of this text appears within the October/November 2016 issue of genealogy Magazine.
KWorks is the online version of JWorks, and KWorks requires an equivalent of three components. GWorks: This tool compares genealogy information to spot shared ancestors. It can use GEDCOMs uploaded by the user, genealogy information downloaded from matches at AncestryDNA. Using the DNAGedcom Client, and genealogy information downloaded from matches at genealogy DNA using DNAGedcom’s Download genealogy DNA Data tool (located under genealogy DNA> Download genealogy DNA Data). See DNAGedcom’s guide for more information about GWorks. Like GEDmatch, you’ll want to watch this and other third-party tools to remain au courant changes.
