    I just purchased an ancestry kit from Dynamic DNA Labs, I have no idea what the ancestry reports even look like. This is my first blind dive ever, wish me luck guys. I will post my results when I get them :p

    Bad news guys, Dynamic DNA Labs just emailed a sample copy of their ancestry report and... I'm not satisfied at all, it's nothing like the other autosomal DNA ancestry companies. I'm gonna have to cancel the order as judging from these sample report results, this test is not worth $100 imo. I'm glad I asked them for a sample report instead of actually waiting blindly for the results and be disappointed after all the waiting. Looks like I dodged a bullet

    Check it out

    I just cannot get on to the Living DNA site. I tried 3 different browsers. I email their support and still waiting. Any help is appreciated.

    23andme sends pre-paid mailing boxes to the EU with a Dutch address. Then they are forwarded to the lab by DHL. It's much faster than regular mail.

    However, I don't like their ancestry analysis at all. I have a match that is quarter Italian and gets 3% and another who is half and gets like 10%. Their method is not transparent at all and, while it seems to work for some people, it can be catastrophic for others.

    Myheritage is like the Ryanair of DNA. It's the cheapest but you have to pay for the postage, you get Oracle-like ancestry and they are constantly trying to sell you overpriced add-ons.

    It's working fine for me on my laptop, what device are you using?

    I don't know which people get really bad results from 23andme, I saw really bad ancestry composition results from other companies, but practically never from this company. The real question for your Italian samples would be what they would score instead. Like its the same as with people complaining about too much German vs. English. That's ok from my point of view, because its basically the same ancestral component anyway. Even their ancestral provinces did improve. So if people which got Italian get something meaningful percentage wise which can be summed up as Italian, it would be ok.
    Like 23andme regularly gives Germans too much British ancestry. But you have to put it into context, its just clear that it is general German ancestry and the exact assignment is hard to achieve. But 23andme gets the segments right for the next, much more important level designation. Those oracle like results can be sometimes better for the regional ancestry, but only with a certain rate, while they often miss minor ancestries and wrongly assign even on the next higher levels, which is all much worse.
    So if the Italian ancestry can be deduced from lets say Italian + Balkan + general South European, its still ok and better than some oracle result which swallows Eastern European, Jewish or Finnish ancestry completely, which belongs to the next level (same level as Southern European).
    Most results from the companies need some interpretation anyway.

    Living DNA just sent me recently this message:

    If you're going by 'Grandparent Locations', they are not necessarily related to ancestry. For example, one of my grandparents was born in Alexadnria, Egypt, but is not Egyptian, but Greek. Additionally, they could be from locations in Italy which are not typically 'Italian' in admixture. For example, north-east Italians close to Slovenia/Croatia are closer to Balkan populations than the typical Italian. People get confused by this but nearly every ethnic group has pretty good results from 23andme. From what I've seen, ones with bad results are ethnic groups from North Caucasus (score way too much Anatolian) and Dodecanese Greeks (score way too much Italian), but even so the results are consistent so once you understand the typical results from an area it's not bad in these cases either.

    23andme labeled a Greek cypriot "Western Asian", and a half Italian half Lithuanian got very little Italian and over 40% Broadly European. There are many other examples where 23andme botched it. They keep reducing their autosomal SNPs which gives less accurate ancestry results.

    Firstly, Greek Cypriots ARE primarily West Asian genetically. They also now have a Cypriot category which gives them mostly Cypriot. However, this can also cause some Greek islanders to score Cypriot now, and I'm not sure if it's actually 'real' Cypriot or just a shared ancestry. So, that result was actually accurate, and was also pretty old. The man in the video was angry at his results, but it was accurate. Anyone with a slight knowledge in these admixture tests knows that Cypriot Greeks are genetically distinct from other Greeks, they have their own distinct cluster.

    Secondly, the Italian/Lithuanian example you give is super old, and was not bad since he clearly wasn't a typical Italian, coming from a region in the north-east. Again, the person who wrote the article doesn't know much about admixture - why would the Italian category capture his 'Italian' effectively when his admixture is very different to the standard Italian?

    You need to provide evidence that the 23andme is getting worse, instead of giving examples that are either old or irrelevant to the current version of 23andme.

    Not to mention, reducing the SNPs may not be a negative. Some SNPs are absolutely useless for deducting ethnicity, so actually reducing the set of SNPs such that they are all useful for either admixture/health analysis is ideal. It might not be great for using on outdated admixture calculators which rely on an old set of SNPs, but it doesn't necessarily negatively influence 23andme's results themselves.

    Hi, I am using a good computer with Windows 10. I tried three different browsers, Microsoft Edge, Chrome and Firefox. Just seems to be locked up and never get to the site.
