I just got my results from AncestryDNA.

What are some ways to find my haplogroup through my raw DNA data?


I obtained my Y-DNA haplogroup from my AncestryDNA raw DNA file using the first method detailed in this link: https://www.geneticgenealogist.net/2016/01/how-to-get-ydna-haplogroup-from.html

In short, it goes through 3 steps:

1/ you convert your AncestryDNA raw DNA file into 23andme format using a small VBS program you can obtain from here:


You simply have to put it in the same directory as your unzipped DNA file (txt file), double click, and it will do the conversion and create a new file in the same directory named yourdnafilename_Edited.txt

2/ You install this program and load the 23andme format dna file into it:


(it requires .NET Framework 4.0, so you might have to install that first)

Go to File -> Save, and save into another text file

3/ Copy the content of this text file into the text area on this website, and run the predictor:


You should get your Y-DNA haplogroup now, which is the result labeled "most likely". If you get BT or F as "most likely" (most people have those, so it's almost redundant), then the next prediction is the most likely (and relevant) for you (there should be more "green" in it than the other options). If you have a problem or a question, either refer to the article linked above, or ask me. Good luck!

    Chris Morley has simplified things even further. Just load your AncestryDNA(or MyHeritage or 23andMe) raw data file here ytree.morleydna.com/extractFromAutosomal and get forwarded to his haplogroup prediction tool. – mario1ua Mar 21 '18 at 9:13
  • I used ytree.morleydna.com with my AncestryDNA raw data file in about 2014 and it worked for me. Don't know if you still could do it today... BTW, the link above (geneticgenealogist.net/2016/01/…) doesn't work for me any longer.) – TJinBC Apr 25 '18 at 18:31

My understanding is that the current normal AncestryDNA product, which tests Autosomal DNA, does not include the Y-DNA or mtDNA SNPs that would be useful for determining your haplogroup(s).

Ancestry sells separate, more expensive DNA tests for Y-DNA and mtDNA:


(Their competitors offer similar tests, so it might be worth shopping around.)

Assuming Ancestry doesn't do the work for you and present a pretty graph or what have you with the results, you would likely be able to download the raw data and figure out the haplogroup yourself using the ISOGG's database:


  • AncestryDNA doesn't sell Y-DNA and mtDNA tests. Only FamilyTreeDNA does. – lkessler May 16 '17 at 4:10
  • Please specify what page on the ISOGG website will tell you how to figure out the haplogroup. – lkessler May 16 '17 at 4:11

They call the y chromosome "chromosome 24".

They only test 885 SNP's though.

They also test 17,604 SNP's on the x chromosome (labeled as chromosome 23), plus 440 SNPs labeled as chromosome 25 that are either from chromosome X or from the pseudoautosomal regions of the Y chromosome.

I do not know a tool, as of yet, for filtering these sections out to determine haplogroups but I'm still searching.


  • I've never seen the Y-chromosome called "chromosome 24". That makes no sense because there are 46 chromosomes, in 23 pairs. The first 22 pairs of chromosomes are called the Autosomal chromosomes. The X and Y (pair 23) are called the Sex chromosomes. – lkessler May 16 '17 at 4:05
  • I think it is artifact of AncestryDNA file format. It is the same csv or tabulated file with raw data like ftdna or 23andme provide. And it is very reasonable to write ChrX as Chr23 and ChrY as Chr24 (for example, file generator uses integer type for chromosome number/naming) – George Gaál Apr 5 '18 at 9:14
  • I am totally sure that AncestryDNA designates ChrX as Chr23 because there is such conversion in useful utilities here: y-str.org/2014/09/autosomal-dna-converter-nix.html – George Gaál Apr 5 '18 at 9:17

I transferred my Ancestry autosomal test to this site and it gave me my haplo group that matched the Y test I had from National Geographic and FamilyTree:
