At long last, they finally come out with a chromosome painter. The most notable difference I see in my results is the way they have delineated segments as Nigerian vs. what 23andme says, although both are of near identical percentages. Also some of the European segments are different between the two, but there are some identical ones. Another difference is Ancestry puts anything in the "unassigned" category with a percentage less than 0.5, which is useful to know if you're wondering whether you have an ethnicity that's not in the report. I have a few that by fall below their threshold but are assigned on 23andme.
Overall, a new neat feature that's been long awaited. What's left is the ability to match our shared segments with DNA matches and decipher our common ancestry from there, and the ability to phase our results with tested parents.
I used this when I first found it, and it was actually pretty easy to use. But, I can’t imagine that it would be easy for people who just do the DNA and don’t do the research.
My paternal grandfather left East Prussia in the German empire in 1910, and didn’t share information on his family or what he left.
I have German on both sides of my family which I know from my research. But because I knew found my grandfather’s parents names and where they came from and moved to and where it is now — which is Russia, since I have a small amount of Russian in me it’s obvious that’s my dad’s side.
My mother’s side came from the Swiss German border area which is much closer to France. So the little bit of French I have in me — probably my mom’s side. Since they left for the US in the 1700s, if I hadn’t have done the research I don’t think I’d have been able to figure it out.
Thanks for pointing this out, Chicagoland, I didn't notice it.
Since Ancestry has my European ancestry all messed up, it's interesting to see they seem to agree with 23andMe about my African ancestry which is only 1.1% in 23andMe, and 2% at Ancestry. Both companies divide it into two groups, Nigeria and Congo region, and the segments from those regions more or less match up between the two companies, although 23andMe detects several smaller segments that were not included in Ancestry. 23andMe shows 7 Congolese segments (4 in Ancestry) and 2 Nigerian segments (3 in Ancestry).
For my equally small amount of indigenous ancestry, Ancestry shows 4 segments, all of which show up in 23andMe, but 23andMe has 3 additional indigenous segments including one on the X chromosome which is not one of the chromosomes included in Ancestry's painting.

I think it's easier for both companies to map the segments of much smaller ancestry, especially if coming from places fundamentally different on a continental level. In my case, while there are a lot of discrepancy between the two companies when it comes to my much larger African portion, the main European and indigenous segments that show on Ancestry are in the exact same positions on 23andme. I also have more segments for both groups on 23andme(49 European and 7 indigenous segments) that's doesn't appear for Ancestry (33 European and 4 Indigenous). Some of those additional segments simply weren't tested by Ancestry and a Spanish & Portuguese segment, as a well as an indigenous segment on 23andme show up as unassigned- not meeting the 0.5% standard for the ethnicity/region they fall under.
Since I tested my mother on Ancestry and have her chromosome layout, I can now determine which of my chromosomes and segments on 23andme came from her versus paternal side, thus better able to filter some of my cousin matches there.

It's been years since I used the two different tests and analyzed them in GEDMATCH to scientifically identify my birth parents, and find my half-siblings. (That was an experience!) Now, I only go out to 23andMe when they email me a request to answer some questions, and I only use Ancestry to explore my adopted family histories. I wish this technology would have been available when I was a young woman. It might've helped me work around a lot of angst and anger I had about my adoption -- and saved my mom a lot of grief.
I thought Ancestry's DNA kit did not use the same algorithms as 23and me. No two company's algo is going to be the same. As the technology of DNA testing evolves your DNA results are going to morph.
My ancestors are Irish and Ukrainian but I have 36% Scottish DNA and only 4% Irish and I don't yet know where the Scottish came from (presently looking for records of the Scottish plantations (1608) in northern Ireland. Records before 1847 are destroyed or not digitized.
You are not going to understand why you have the DNA results you got unless you spend some time actually making a tree. Also check back on your on line results to see what has changed, if anything.
