German Project Progress Update

We are extremely excited to share the progress we have made with our autosomal DNA test for people with Germanic ancestry. We would like to thank everyone who participated in the survey. It has been incredibly helpful to us in understanding what German-speaking parts of Europe we have improved our test performance in.

Our Science team has been working very hard to update our reference populations with more German samples. The new panels have undergone rigorous testing to assess their performance and accuracy.

Process

As part of the testing process, we surveyed Living DNA customers with German ancestry to get feedback on their results. First, we collected feedback on their current results and their ancestry expectations based on their own research. We then reprocessed their data using our new estimation method and collected feedback again. We analyzed all responses based on the provided grandparent birthplace information. This helped us to identify what regions of Germany we are able to pinpoint and where we need to collect more data from.

At the moment, we are able to estimate several Germanic regions. DNA samples that we have processed using our updated estimation method, have already been given an estimate for what part of the large Germanic shape their recent ancestry comes from. However, as we are undergoing a major rebuild of our ancestry results portal in order to make your Living DNA experience easier, we are not able to display the new Germanic sub-regions yet.

How does this affect me?

As soon as the new results portal is ready, we will be able to display the exciting sub regional breakdown results. We will be re-processing everyone’s data at no extra cost with our new method once our infrastructure rebuild is complete.

Statistics & Feedback

We wanted to share with you some recent statistics from our survey participants, direct feedback and some examples of how the results now look

91% of survey participants say that their estimated German percentage has increased 80% of survey participants say that new ancestry result reflects their expected ancestry better than the old version

Overall, the results seem far more plausible to me. I would find it helpful if you could also explain the correct interpretation of the results in German

From my point of view, the new evaluation results better represent my family history. My father comes from the Gdansk area, a region in West Prussia that was heavily influenced by immigrants from the UK and Ireland. Thank you for the opportunity to have an active part in the adaptation of your evaluations through this survey!

Here are some examples of how results have improved for those that have German ancestry

Thank you again for all your help with this project and the feedback you have all provided.
