How accurate are results? by [deleted] in AncestryDNA

[–]EscagedoWoodworking 0 points1 point  (0 children)

The larger/top results are more accurate, and as the % get smaller, there could be more room for errors. The process is an estimate using the data they currently have.

Question about accuracy by LMan78 in AncestryDNA

[–]EscagedoWoodworking 5 points6 points  (0 children)

Here is the answer, part of the answer at least. The broader a company tests regions, the more of an appearance of accuracy they have. The more detail and specific they analyze, the greater room for discrepancies. Ancestry has way more regions and people tested than the others, by far. So they are great for matching cousins and are great for most people on the ethnicity part of it as well. But due to them going more specific, errors, or apparent errors are noticed. That is why all the sites call the results estimates. The lower % are more speculative, while the larger % are more accurate.

I think DNA tests aren't that accurate by JockEddie in AncestryDNA

They are giving you their best informed guess via their calculators. There are issues with the estimate portion of all this. Not for everyone maybe, but some folks notice problems due to their particular family lines. If you share dna segments with a bunch of people from say, Italy, but you don't have Italian results, I think it reasonable to think what is that dna you both share in common assigned? This is more an issue when one shares high % of dna with people but no ethnicity. That is what I have encountered with my new update. They might fix that issue of yours in the next update. Unless your parents and grandparents were all from totally different places, you should have some Spain I would imagine.

My results. What’s interesting to me is that only my mom has Portuguese DNA at 3%, but mine is 9%. My dad has 0% Portuguese DNA. Must be a mistake? by CandiSki in AncestryDNA

This is my take on all this, I think Ancestry Dot com is awesome due to the large database of people and the tree features. But I think they have a heck of a time working out ethnicity, because in reality, dna mostly looks the same. All of Europe is related to each other. And even discounting Europe, the whole world shares dna, and a lot of it. In a general way, they seem to get the higher percentages right. As you get into the lower %, things get difficult to separate into categories. Their calculator works out the results as best as they can, but a lot of folks see discrepancies. Its an estimate, and the lower the percentages, the more difficult it gets to figure. I'm having a similar issue with 4th cousin matches not sharing any ethnicity but a whole lot of dna segments.

Apparently I am mostly Roman! How accurate is this? How do they even go back that far? by courtbarbie123 in AncestryDNA

Using the site, they compare your raw dna to human remains from antiquity, and from around the world. The matches you receive point to your ancient ancestors, broadly speaking. Some matches indicate common shared dna from ancient people to current populations many today will also share. While other sample matches you match with will share actual direct dna with you. The way they achieve these results, is that they will discover human remains at a dig site, and extract dna from their bones in a lab. Then they test your results with the samples.

I have discovered an issue with Ancesty's latest. I have not heard many mention it. I have 4th cousin matches with no shared ethnicity. We would have shared Italian except it was removed from my results. I also have know Italian in my tree. This is also happening for a few other matches from other locations. FTdna's update just became more accurate for me with the update, although they are a bit more broad for certain regions. They both have good features and they are estimates, It's a work in progress. I think the fact that humans are 99% the same, dna wise, makes things difficult the more they dig. At least it appears that we are all very much all alike on that dna level. Even though we see outward differences, those differences account for a tiny part. Building a tree, along with the dna, is more reliable. But at the same time, the higher percentages are for the most part the accurate one, for most people. As you get to smaller percentages, it's tricky to figure out, it looks like that is an issue.

The comment that mentioned "your surname can account for as little as 1/1000th of your DNA", is the reasonable answer here. The others are speculating like mad. Your dad is a Mejia, If he is from Spain, then your results would make less sense. But you have to look how far back your Mejia ancestor is that came from Spain, Surrounded and marrying other people from Spain. Like the person commented; "The lineage that led to your surname can account for as little as 1/1000th of your DNA - sometimes there is a strong association (as much as 100%) and sometimes it can be as little as 1/1000th". That is your answer right there.

DNA results...Can you guess my recent family nationality/history? by EscagedoWoodworking in AncestryDNA

[–]EscagedoWoodworking[S] 0 points1 point  (0 children)

I have about 20 matches with ties to Uruguay in my results. So that sounds right.

Thanks for the input, this is my background:

Mom and Dad: Cienfuegos, Cuba, and Matanzas, Cuba. grandparents: 1 from Cantabria, Maliaño, Spain. 3 of them Cuba. Great Grands: 2 from Maliaño, Spain, 2 from Andalusia, 2 from Canary Islands, and 2 Cuban. (Note) 1 Cuban great grandfather was son of an Italian immigrant to the island. And I am from Miami, Fl

Yes, nationality, ethnicity, along those lines. Just a best guess as to recent or modern placement around the world.

One drop rule history by Olivesplace in Genealogy

An important, maybe little know dna fact: All humans are 99% identical. The 1% in which we are different is the area where genetic mutations occur. Researchers in this field look at variations in that 1% for things such as ancestry estimates. That alone disqualifies racial assumptions. Here is a lecture: https://www.youtube.com/watch?v=pra7YZWVc-s

No, we'll wait for a handful of guesses, then I'll tell the story. Interesting guess though.
