While trying to find information about my family's Y DNA haplogroup, I ran across a post on a message board stating that the SNP testing at 23andme was accurate but that they used the 2010 tree. Hmm, I remembered reading a great blog about extra stuff you could do, and I went back to it. I thought I would blog about it so that other 23andme user's would know how to get the latest haplogroup based on the 2015 tree. To be honest, I do not know if there are snp's not tested by 23andme that determine haplogroups.
1. Download your raw data from 23andme.
This is found under the Browse raw data option on the upper right hand drop down menu. Once the data is downloaded, you need to extract the zipped file.
2. Download the 23andme to y snp program.
This wonderful little program is found here.
3. Open the 23andme to y snp program and then open your raw data file from within the program. It will analyze the data. Save this new information to a txt file from within the program. I usually save it in the same file as the raw data that is unzipped so I can find it again.
4. Download the chrome extension, ISOGG Y tree add on, a link to it is found here.
5. Open the ysnp file you just saved. Select edit, select all and copy.
6. On Chrome, go to the three lines in upper right corner, and click on it. Select settings in the drop down menu. Then select extensions.Find the ISOGG Y tree add on in the list. Under it there will be a link for options. When you select this you will get a new window. A sample is already in slot 1. You can add up to 9 more people's y snp data. Put the name of the person and paste the ysnp file data you copied from the text file. Close the window.
7. Go to the ISOGG Y tree. You can find it here. You will see letters representing the first letter of the haplogroup. There are also links for the Y tree from previous years. The add on will work with all of them.
Click the letter that corresponds with the haplogroup you were assigned by 23andme.
8. Once you get to the haplogroup page, the add on will load. In the upper left hand corner when it is done you will find a drop down screen. Select the name you want to run the program on. When it stops saying loading, scroll down the page. The SNP's will be highlighted RED or Green. Green means you have the SNP, Red means you don't. Simply put, the last green highlighted snp on the page is the one that corresponds to the haplogroup to it's left, and that's the haplogroup your dna is at this time.
As a result of this, my mom's paternal line went from R1b1b2a1a1d at 23andme to R1b1a2a1a1c2 in the 2015 table.
Hope this helps.
