DNA “Begging” Letter



 

Dear DNA Relative,

I am getting ready to beg, which is something I don’t do often. You are a DNA match to me, either in FamilyTreeDNA (FTDNA), 23andMe, or AncestryDNA. Those are the three DNA tests I have taken. Guess what? There is a wonderful FREE online DNA tool called GEDmatch. You can access the site at www.GEDmatch.com. Did I mention that it is FREE! Although I have stressed its importance in other blog posts, this letter is to re-stress the importance of uploading your raw data file from any of the three aforementioned DNA companies to GEDmatch. Yes, this is indeed very very important. Therefore, please upload to GEDmatch. Pretty please!

First, I would like to briefly list a few reasons why uploading to GEDmatch is important. Secondly, I will provide some instructions on how to do so.

Reasons to Upload to GEDmatch

1.    To gain more DNA matches with others who have tested with a different company but uploaded to GEDmatch. You might even gain some high DNA matches. This is especially important for adoptees. A long lost sibling, parent, aunt or uncle may be in GEDmatch.

2.    To be able to compare your DNA to known family members in order to determine how you are related. This effective process is called triangulation. This can be performed in 23andMe and FTDNA but not in AncestryDNA. This is a good blog post that explains this process: http://blog.kittycooper.com/2015/02/triangulation-proving-a-common-ancestor/ Here’s a scenario: Let’s say that you match me in AncestryDNA. Once you upload to GEDmatch, I compare you to both of my parents and determine that you match my father. Not only that, I compare you to other known relatives and determine that you also match my father’s paternal second cousin in the same area on one of our 23 chromosomes. Then, I know that you are related to me via my paternal grandfather. We can then take a closer look at his family tree to try to determine exactly how we are related.

3.    If you have taken the AncestryDNA test, you do not even know exactly how much DNA you share with a DNA match. You only get a “confidence score,” which is not that useful, in my opinion. DNA is measured in units called centimorgans (cM). The more “cM” you share with someone, the closer the relationship, in most cases. In GEDmatch, you learn how much DNA you share with your DNA matches. You can also use ISOGG’s DNA statistics chart to determine a possible relationship. Those statistics can be seen here. (Note: Ancestry DNA now shows the amount of DNA shared with your match. Just click on their DNA profile by clicking "View Match," and click the "i" besides the confidence score.)

4.    You have a plethora of analysis tools in GEDmatch to learn more about your ancestry composition. You wanna see if you truly have some Native American ancestry? You can do so in GEDmatch.

5.    You can even determine if your parents are related to each other. Yes, for real. Many people did not know that they married their cousin.

6.    You can do X-chromosome comparisons in GEDmatch. You can’t do that in AncestryDNA. X-chromosome matches are revealing because X-DNA is passed down via certain lineages. This helps to determine the family connection. For further explanation, read this blog post.

These are just a few reasons why you should upload to GEDmatch. There are others, but I know that your time is very important. The reasons I just listed are the most important ones, in my opinion. Now, here’s how you can upload to GEDmatch:

Uploading your 23andMe Results to GEDmatch

1. In 23andMe, in the top right corner, click on your name and click on "Browse Raw Data."


2. Once that page opens, look underneath your name in the top right corner and click on "Download".

3. Re-enter your password and enter the answer to the secret question. Then, choose your profile. For “Data Set,” select ALL DNA.

4. Remember the spot where the raw data file is saved on your hard drive.

5. Go to www.GEDmatch.com. Register a new account. It will send a verification code to your e-mail address. 


6. Once in GEDmatch, under "Autosomal Raw Data," click on "23andMe."

7. Complete the fields. You will see an icon at the bottom where you are asked to upload your 23andMe raw data file.

8. Then, watch it do its work. Do not close your browser while it is processing.

9. Once it is done, you can do certain things in GEDmatch, like One-to-One Comparison, but not everything until batch processing is 100% complete. That may take several days.

  1. Great article Melvin. As a newbie to DNA I would have liked to see a link to an additional piece to this article. I would have liked to see a side by side comparison of the different types of DNA, what the differences mean so those such as myself who are still thinking about DNA testing could understand which of the DNA tests are suitable for someone like myself who can only afford to do it once. In addition, a link to the different sites performing DNA testing would be nice. I did see you on 'Who do You Think You Are' as it is on my to do list when it comes on. It is a great show and I love to see who they discover. Thanks again for the article.

  2. Richard, in your circumstances I would do the ancestry DNA test and upload that to GEDMatch. You will learn as you go. I'm not a huge fan of ancestry as a business but they do have a 10% off sale until June 21. Search the web for a coupon for free shipping. Or wait to see if they have a 20% off sale later in the year. And don't forget to look for a free shipping coupon code. The testing companies are AncestryDNA, FamilyTreeDNA (FTDNA), 23andMe

  3. After you do gedmatch, try this. It's also free and a lot of fun. https://genomemate.org/

  4. Also, use your ancestry dna kit number for your alias, it makes it easier to link to the gedmatch data.

  6. I have spent 2 hours trying to get my raw data file uploaded. it is from Living DNA and 2472 bytes. Finally i stumbled across the necessary information on minimal file size that was not given in the error message telling me to check i had the correct file and try again. it ought also to have been revealed that it was the autosomal dna file that is to be uploaded to Gedcom Genesis. now i shall hunt for the DNA for dummies link i stumbled across. my haplogroup subclade is T-Y11151 and motherline haplogroup subclade Hig1. also you need to know that if you open a spreadsheet created in office 2013 micros-t will generously change all your office files to office 2013 so that you can return the generosity to micros-t by purchasing office 2013 .unless of course you prefer a version that micros-t so generously has removed for you all the functions from (such as continuing to use or copying, well yes indeed all functions).
