Thank you! I’ve tested with 23 & Me but I think I’ll test with Ancestry now as well. I’m adopted and have no known relatives as references.

Some of those small segment/cM matches can have a significant impact on your tree.
I found a 9cM cousin with a tree that had the same paternal surname for a seventh! generation ancestor with all their children including my 6th Great Grandmother! I had the incorrect parents to her in my tree for many years thinking the records were correct.
Distant DNA matches can really help break down brick walls.
So people when you get your DNA tested, PLEASE CREATE A TREE!

I have a question and forgive my ignorance but if raw data never changes and I submitted a sample to ancestry is there a way to download raw data from them so that I can upload it to different sites or is that not advisable

[ahata]

Africa AncestryDna results are not accurate. Results depend on reference population Ancestry Dna have in their reference panel.

For example, AncestryDna doesn't have Nilosaharian reference population.

An example:

AncestryDna tend to make South Sudanese look like they only descended from Mbuti Pygmy and West Africa/Bantoue which is very misleading since South Sudanese are distinct from West Africa and distinct from Bantoue.

[GothamCityStills]

There’s no way that any of these tests are accurate. I have taken literally hundreds of tests. They always change and contradict themselves. Leaves me more confused than I was before I started this whole journey.

[tomjones]

Can you use any of the documents that you get from these companies in a legal Setting?

[GothamCityStills]

These tests get more Euro-centric in my ethnicity report. I am not 100% European, at least I am pretty sure given that my GGfather was adopted. I have gotten wildly different results on probably over the 100 tests that I have done on myself over the last ten years or so. Do you have any idea why?

[Calatriste]

Where is this link to a free guide..(?)

[sclips]

what would happen if a little bit of someone elses dna got mixed in the tube?

[tracylynn]

Umm I have thought about testing again just to see if it changes... Will CRISPR change that in the future? I wonder... I'd say dna does change but I am guessing there either naturally from environmental factors ect ect ect or the new editing of the genes.. as always ure this will be a great video and DNA still amazes me daily ♡
Yes I know I come at yall with some big questions..lol I just find it all so fascinating and the great things we are learning to do that also scare me a bit too;) pretty powerful ability they have uncovered

[lawrencejackson]

What could explain a match at 17-25 cms with no shared matches?

[rightofcl]

A lot of people who are realistically my third cousins don’t pop up on my results

[patriciayohn]

I can't imagine you can change your DNA however, the matches you receive can change by how many more people test and gee all of a sudden you get more matches.

[coquiangel]

I'm confused on matches and ethnicity.
I'm adopted, I read somewhere, my birth father was Puerto Rican/or Afro-Latino.

Ancestry, doesn't show this except for distant matches, that have Cuban, Dominican, Puerto Rican, etc
Does that mean that it's correct but not enough data?

Also, I've tested with 23andMe and it's a bit more different than Ancestry; with 23, there's recent ancestry from Jamaica.
Some of the matches there also have PR either in their DNA or descendant.

[konnierad]

Please do a CRIGENETICS test please and compare the results. My results were dramatically different with this company. My results for 23andMe and ANCESTRY DNA were similar. I would love to know why

[stevechrismillersarro]

What do you think, is more Accurate? Now... this has to with, Ancestry DNA site, because, they have the Side View, and they also have it, where you can see, what Ethnicities, you match with, with that Pacific Cousin. Now, on My Mother site, The Sideview says, all her Irish, is coming from, her Mother, (which is correct) But, when you go on, the Match list, and you click on, Parental Matches, some of the cousins, match Ireland. It's a match, because, its highlighted, in Black, (But Ireland, shouldn't be a match, on My Mother's Father side). So why does, My Mother match, a cousin, on her Father side, when the Side View shows, 0% Ireland, on the Parental, side. All of her Ireland, shows, that its coming from her Mother? Does not make sense, Match Ireland, with a cousin, on the Parental section, in your Match list, when the side view, from the Prenatal Side, says, 0% Ireland, and all of her Ireland, is coming from her Mother. It's not just Ireland, its, England in Northwestern Europe. And other Ethnicities to. The Side view, I think, shows the correct Ethnicities, Coming from, her Father, and mother. The side view, currently shows, Only, Jewish, Balkans and Albania and Greece, and that Definitely Correct. Other DNA sites, show more, Mediterranean Ethnicities, Middle Eastern, West Asian, Iberian. But what it shows, for My Mother's Father, on Side View, the Ethnicities, is correct. Most cousins, on My Mother's Father side, when you go, to the Match list, and go to the Parental side, (Most) cousins, on that side, match the, side view. But... there's still, a good enough cousins, on Parental side, that shouldn't match, with the, common Ethnicities, like... Ireland Scotland, England.my Grandfather, is only, Slavic and Mediterranean Ethnicities.

[paulbolin]

These test are nationality test more than anything given they deal with locations. Place does not define who or what. There are only four original ethnicities and combinations of those. Just look in the mirror.

[gaylecheung]

KMSL, You need to even ask that question in 2021, Infancy of DNA genealogy tracing

[sr]

It totally depends on which areas each DNA company is testing and which kind of tests are being used. Also if they are reporting where your ancestors lived or reporting what ethnicities you are. I am from Madeira and there were mixed races and ethnicities there so telling me I am 97 percent Portuguese probably isnt really accurate. Also Ancestry removed my North African ancestry.

[dawnemile]

The results are only as accurate as the one doing the reporting.
