Why you should get AncestryDNA over 23andme

[Pennywise]

The OP I explained the difference between AncestryDNA and 23andme, but I left out FTDNA because it sucks so much that it isn't even worth it. See here: http://www.theapricity.com/forum/sho...-they-serious-!

Basically, AncestryDNA = most accurate, 23andme = somewhat accurate, and FTDNA = usually shit

I read it. I guess only 23andme tell your Y-DNA, right? I know some ftDNA customers and they were fine with it, I'm not sure about the issue of your results.

It used to be good, like my results when I got them. However they made bad updates and it's shit now.

AncestryDNA's database is not much smaller than 23andme, the utilities can be done elsewhere with raw data, and like I explained in the OP, AncestryDNA's AC is much better than 23andme's.

I do plan on getting 23andme as well, just to see if I find any new relatives on there. I'm not the typical customer, though. I have an obsession. For the average person, AncestryDNA alone suffices.

Nope, I have access to one account at AncestryDNA and I've seen is that the AC was pretty neat on for that person who has both northern European and Italian ancestry, but there is no such thing as a global similarity plot, paternal and maternal haplogroups (although limited) cross comparing matches, countries of ancestry and DNA relatives matches per country.

Maybe their AC would be more interesting for someone from Turkey I don't know about that, but I never heard before that their system of predicting ancestry was better than 23andme.

The Middle Eastern at 23andme would be 'West Asia' (Caucasus & Middle East) for southern Italians at AncestryDNA.

I agree, Yes. Same.

My results got like 3 updates. so some little bit of change happen with them over time. Which got me a bit confused. But I take them with a gran of salt now.

So uhh, just to get things straight: you're basing your arguments against 23andme being inferior to AncestryDNA solely on your own results projected from a multi ethnic background, am I right ?

Well he's just pointing out to FTDNA's ''MyOrigins'' being less good than the other tests, which is where he has a point but the haplogroup tests are the best at FTDNA because they go much deeper than most other companies.

If this works you're the man !

yeah but you have to pay extra money for both mtdna and ydna results. and it's not that cheap either especially if you are ordering it from out of america. 23andme autosomal test show your y-dna haplogroup for free.

Yep, it depends on your wishes and wallet.

I am so disappointed in 23 and Me! The info and sample results that they show the prospective buyer are much more detailed and specific than what you actually get. Also, they neglect to inform the prospective customer that the results you will get will have 3 views, all of vastly differing accuracy. The results that they label as "Conservative" has an accuracy rate (by their own calculations) of 90%. The other 2 composition views are "Standard", with a 75% accuracy rate, and the third is "Speculative" with a 51% accuracy rate. Accordingly, the details of your genetic ancestry and countries of origin drastically decline with the increase in the accuracy rate. So the "Speculative" composition contains a much more specified and detailed breakdown whereas the much more accurate "Conservative" composition is exceedingly general and broad. So to summarize, the "Conservative" results are the only ones worth anything because the others are too speculative, but conversely, they are also the results that basically don't tell you a damn thing. To illustrate, my "Speculative" results were as follows: 43.8% British & Irish, 15.4% French & German, 8.0% Scandanavian, 0.1% Iberian, 0.7% Broadly Southern European, and 0.1% unassigned. Now compare to my "Conservative" (and much more accurate, although vague, results): 8.5% British & Irish, 54.1% Broadly Northern European, 34.8% Broadly European, and 2.5% unassigned. So basically I paid $108 to find out nothing any more specific than what I already knew-that my ancestry is European, British and Irish. I would not recommend wasting your money and time (you will spend a GREAT deal of time on this) on this or any of 23 and Me's competitors as their accuracy rate and data base is much less than 23 and Me's is.

Is there any data demonstrating that AncestryDNA's genetic breakdown uses higher confidence levels than 23andme? (Completely different from an "accuracy rate" btw, this reviewer could use a thorough brushing up on basic statistics.)

Here, we're showing a 70 percent confidence threshold. We'll run across the chromosome from left to right, and ask whether any population has confidence exceeding that threshold. You can see that with the exception of the blue European stretch, we exceed this threshold over the majority of the chromosome. These regions will contribute in proportion to their size to the overall ancestry percentages: For example, consider the green Native American segment near the right end, and that it works out to be 0.26 percent of the entire genome. Even though we have some probability that the segment comes from other regions, the Native American proportion exceeds the current 70 percent threshold, and so we'll add 0.26 percent Native American to the overall ancestry percentages.

In the case of the European segment, no single population exceeds our 70 percent threshold, so we won't report that DNA as coming from any of those populations. In this case, we refer to our hierarchy of reference populations. For example, we have a "Northern European" group that contains three reference populations: Britain & Ireland, Scandinavia, and France & Germany. We'll add up the contributions of each of these subgroups, and see if the total "Northern European" contribution exceeds the 70 percent threshold. If it did, then we'd report the region as "Broadly Northern European".

In this particular case, the Northern European reference populations do not exceed 70 percent. So we go up another step, and see if the contributions of all the European populations exceed 70 percent. They do, and so we would report this region as "Broadly European."

You can see the entire hierarchy in the Ancestry Composition table by clicking "Show all populations."

In regions where we go all the way to the top of our hierarchy, but no group of populations exceeds the threshold in place, we'll report "Unassigned."

We've built in three confidence thresholds to Ancestry Composition. These are Speculative (51 percent), Standard (75 percent), and Conservative (90 percent).
