When comparing your matches on any segment, you’ll wind up with a group of people who match you and each other on your maternal side, a group on your paternal side, and “everyone else” who is IBC. Regardless of why, they are not a legitimate maternal or paternal match to you.įor example, you can see that the identical by chance (IBC) match to you, above, won’t match the legitimate maternal or legitimate paternal matches. Conversely, you can match the DNA of their parents intermixed as well. In other words, they are identical by chance (IBC) because they just happen to match the DNA of both of your parents intermixed. IBC matches DO technically match you, but accidentally. They will not match either of your parents individually. Identical by chance matches will match you, because they have the same DNA as both of your parents that you carry – interspersed.Legitimate paternal matches to you will have all Cs in this location.

Legitimate maternal matches to you on this segment will have all As in this location.

You inherited half of your Mom’s DNA and half of your Dad’s. You can see how matching works in this example of 10 DNA locations.

People that are identical by chance (IBC) where they match you because part of the DNA from your Mom’s side and part from your Dad’s side just happens to look like their DNA (or vice versa.).

On each segment location of your DNA, you will match: Matching and Triangulation help you sort out legitimate matches, and which ancestors that DNA segment comes from.

Triangulation in Action at Family Tree DNA.

I wrote about triangulation at each vendor in the following articles: Segment matching is also the first step in triangulation which allows you to confirm descent from common ancestors with your matches. Your matching segment file consists of hundreds/thousands of rows of this information.ĭetermining who matches you on the same segment is important because it facilitates the identification of common ancestors.

Here’s an example that includes the match name, chromosome, start and end location of the match along with the total number of CentiMorgans (cM) and total SNPs in the matching segment. The matching segment file provides you with information about exactly how and where you match each person. Some Ancestry matches will have transferred elsewhere as well, and you can take advantage of your matching segment information. You can’t obtain this information from Ancestry, but you can transfer your DNA file to other vendors such as FamilyTreeDNA, MyHeritage and the third-party site, GEDmatch where you’ll receive additional matches. Third-party tools that did this for you have been banned by Ancestry, under threat of legal action, so this information is no longer available to Ancestry customers.

Unfortunately, Ancestry does not provide any segment data at all, nor do they provide a way to download your match information.

In this article, I’ll provide information about how to download your matching segment and match information file(s). Some of the answers in the table above need caveats because each vendor is different.

I have provided step-by-step information about how to download your raw DNA data files and upload them to other vendors in a series of articles that you can find here. This type of information is not uniformly available from all vendors, but is available as follows: Vendor

Match information files that provide you with additional information about your matches.

Matching segment files which detail your matches, segment by segment with people whom you match.

Raw data files needed for transferring DNA files from the company where you tested to other testing or analysis/comparison sites such as FamilyTreeDNA, MyHeritage, and GEDmatch for matching and other tools.

Genealogy customers need to periodically download as much as possible.

There are two or three types of data that testers may be able to download from DNA testing sites.
