Uploaded Your Dna Test Results to Gedmatch
In this tutorial commodity, we're talking near what is GEDmatch, how to upload your Deoxyribonucleic acid information from unlike DNA testing services into GEDmatch, and explaining each function and how it can maximize your DNA relative match. GEDmatch is one of the about popular tools to track down family unit members and learn nigh your family history. Using raw Deoxyribonucleic acid data that y'all can get from a genetic DNA testing kit kit from companies like 23andMe or AncestryDNA, GEDmatch allows you to dive deep into techniques used in genetic genealogy.
Although GEDmatch is an extremely powerful tool, there is quite a learning curve on how to utilize GED match effectively. Plus, keep in listen that GED match was recently purchased by a company that specializes in cold cases, crime scene forensics, and uses the genealogy site to solve crimes. Follow forth with us to see exactly how y'all can get-go using your raw DNA data to inquiry your family unit history using GEDmatch!
What Is GEDmatch?
GEDmatch.com is a slap-up family unit finder tool for people who are interested in finding your relatives for Free. The website offers a suite of professional-course genealogy research tools that are non for the faint-of-heart!
GEDmatch got its roots when at-domicile consumer genetic DNA testing services started allowing users to download their raw data. With this genetic information, GEDmatch can run a suite of statistical techniques to assist you fully understand your genetic heritage. Previously a non-turn a profit company, the company was recently purchased by Verogen, Inc., a visitor that focuses on forensic evidence for law enforcement.
The database on the GEDmatch site was one of the first DNA databases that police used to identify criminals - namely the Aureate Country Killer, who had avoided regime for 40 years! Verogen clearly valued GEDmatch's database, which was purchased along with the company. While site policy nevertheless allows y'all to "opt-out" of giving police access to your information, having a database police enforcement tin can use is clearly now a goal of the company. Even distant relatives with Dna in the database can better police enforcement matching and information technology makes genomics a useful tool for catching criminals.
Is GEDmatch Safe?
Though GEDmatch started equally free service allowing users to search for family members using their DNA data, the company was purchased by forensic company Verogen. Though the acquisition raised some concerns nigh user's DNA privacy and the transfer came with some bug, the company still provides users with the pick of opting-out of police enforcement searches. The company seems to be abiding by this policy, as there was only ane initial outcome that resulted from a breach in the arrangement. The upshot has been resolved, and no new reports of unwanted law enforcement access take been reported. However, you may want to know more about this incident to put your mind at ease.
In July 2020, the GEDmatch database was breached by hackers. As a result of this incident, the privacy controls on millions of user accounts were overridden. For about 3 hours, this breach allowed law enforcement agencies to run across the data of millions of users who had not given their consent. While the site was shut downward rapidly and the privacy settings were restored, the alienation started calls for GEDmatch to exist more transparent about their cooperation with law enforcement. For example, companies like 23andMe and Ancestry regularly publish reports that detail the times they were required to disclose user data for legitimate legal reasons. This seems to accept been a sometime issue for GEDmatch, though caution is warranted if y'all do not want law enforcement officials to access your private data without a search warrant.

This is where all of the free tools reside on GEDmatch. Simply click on each of the tools to get started. Remember: you will need your kit number for virtually applications.
GEDmatch is commonly used past professional genetic genealogists for genealogy research. The core features include:
- 1-To-Many DNA Comparison Issue: Helps you compare your genetic contour to users in the GEDmatch database. Emails are provided so you lot can quickly contact them if you get a hitting. This is a simple and keen resource for telling if you are related to anyone in the GEDmatch database.
- One-to-One Autosomal DNA Comparison: This helps you lot narrow down the comparing with ane specific relative member. Apply this to confirm how much Dna data y'all actually share with that person before yous reach out.
- Admixture (heritage): This is a well-known DNA assay for identifying your ethnic roots. Like Beginnings Dna and 23andMe, information technology shows the proportion of your DNA coming from a particular ethnicity/geography. It'southward interesting to compare these results with that of other ancestry DNA testing kits.
Even so, there are numerous other tools listed on the GEDmatch homepage that you can employ for different purposes (as pictured beneath). For first-timers, we recommend starting out with the iii tools listed above (boxed in cerise in the image below). Nevertheless, in one case you get accustomed to the costless tools, consider upgrading to the Tier ane bundle to get some really incredible tools.
GEDCOM Files

You may even be able to meet where you shared a mutual ancestor!
Tier i Tools
Though we won't get into how to use the advanced GEDmatch DNA tools hither, it is worth noting: they are pretty cool. Here is a short description of some of the coolest tools GEDmatch users get admission to:
Lazarus : Substantially, you can recreate a dead person's genetic code using samples from their shut relatives. While information technology won't bring them back to life - it is very helpful for using DNA information from an autosomal DNA test to do deep genetic genealogy research.
Phasing : This tool sorts out your chromosomes past using information from your mother and/or father. This allows you to encounter exactly which parent gave yous that kleptomaniacal olfactory organ!
My Evil Twin : Your parents could have created many versions of yous, based on which genes they passed on. This simulation essentially recombines your genetics to judge what traits your "evil twin" would accept carried.
There are many other traits available in Tier 1, allowing you to explore specific segments of your Deoxyribonucleic acid and many other statistical analyses!
How To Understand The Results
In one case your results are ready, you are able to explore a number of features on GEDmatch. Here are the 2 main tools:
How to Find My Deoxyribonucleic acid Relatives?
1. One-To-Many DNA Comparing Result
When y'all click "Ane-To-Many DNA Comparison Result", you can run across a list of contacts like beneath.
How practice you evaluate the results to determine who is a potential relative? Check "Overlap and Total cM" start.
"Total cM" is the total length of all substantial Deoxyribonucleic acid segments you share with a Dna match. "Overlap" is the total number of overlapping SNPs that yous share with your match. SNPs are "single nucleotide polymorphisms." You tin think of them but equally Dna messages important in determining your unique genetic profile. Therefore, the larger the number of centimorgans you share with another user, the more than closely you are related.
The table* below summarizes the total cM expected from dissimilar degrees of relations within the family. For instance, if your parents' data is on GEDmatch, they should evidence up as a match with over 3000 cM shared. If you do information technology with cracking-grandparents, it would exist around 464-1486cM. Or 46-515cm with a 2nd cousin.
However, GEDmatch likewise gives yous the power to modify and modify this search. You can learn more about how your "match thresholds" tin can modify your results on the ISOGG Wiki.
*If y'all want farther details, DNApainter's comprehensive nautical chart of cM calculator does a good chore of explaining this. Notation that DNA information files and their coverage of the genome differ across companies, so results may inevitably not be 100% accurate.
In determination, by checking "Overlap" and "Total cM", you may detect people who share a meaning amount of Deoxyribonucleic acid with you — people who potentially are your newfound relatives!
2. One-To-One Autosomal DNA Comparison
Once you discover someone who shares a good chunk of Dna data with you, you lot tin can start earthworks into the details of your Deoxyribonucleic acid relationship with them. The image below is from the 1-To-One DNA Comparison Consequence: it gives you a visual representation of which segments of your Deoxyribonucleic acid you share with that person (chromosome browser). What y'all want to see is how many blue chunks do you accept.
This 1-on-1 matching can actually help you narrow down who y'all are related to and how much Dna yous share with that person. You can also commencement to track which segments of Deoxyribonucleic acid you share with different people - niggling puzzle pieces in the story of how yous came to exist.
A Review of What Else Can Nosotros Do With GEDmatch?
1-To-Many DNA Comparison Effect and Ane-To-Ane Dna Comparison Result are crawly tools to start with. Besides those, here's our recommendation for what else to try.
Effort out Admixture / Oracle with Population Search.
This helps you acquire what genetic ethnicity you have based on publicly available genealogy databases such as MDLP, Eurogenes, Dodecad, etc.
Here is a summary of the recommended databases to use based on your ethnicity:
MDLP — European, American
Eurogenes — European, American
Dodecad — Eurasians, Asians, Africans
HarappaWorld — South Asian
Ethiohelix — African
puntDNAL — (Unknown)
GedrosiaDNA — Eurasian (Indian and Asian)
Are Your Parents Related?
This "fun" tool allows you to run across if your family is prone to inbreeding. You would be surprised - it is more than common than people think, though the human relationship is usually very distant. This tool substantially compares each "stage" (maternal or paternal portion) of your DNA to run across if they are related to each other.
X-DNA Comparison
Using FamilyTreeDNA X-Dna data, y'all can compare your X-Dna directly to other users that have uploaded their data.
Ane to One X-Dna Comparison is a unique feature that enables you to do the aforementioned comparison as "One-To-I Dna Comparison", specifically for your 10 Chromosome. The main I to 1 comparing tool analyzes autosomal DNA, which is your numbered chromosomes commonly used by ancestry Dna companies. Y-Dna tin can trace your paternal line (father'south side), X-DNA does the same for your mother'due south side maternal line.
The I to Many X-Deoxyribonucleic acid comparing allows you to compare to all the users in the database at once and see if yous share the same haplogroup and what percentage of the X-DNA you share. For males, X-Dna is very telling of their maternal DNA ancestry (similar to mtDNA).
You can learn more nearly how to use this tool on this post as well!
