Accuracy of AncestryDNA outside British Isles
As the title says, I want to discuss Accuracy of AncestryDNA outside the British Isles. 75% of my heritage (based on family tree) goes back to the British Isles, and a little over 50% of my heritage is British. Now, I was very pleased with the results during the last update because they were very close to my family tree and matched chromosome and recombination inheritance, and this applies to my parents and grandparents as well. I am not saying they are perfect, but they were still very good results.
However, I browse the subreddit and I see people of non-british isles heritage and they do not seem very accurate. Especially Russian and Ukrainian Results where they are scoring a bunch of Polish. I look back into my tree and I see my German is not very astute either and seems very diminished. The best example I can think of is France, where my grandmother's 2nd great grandfather was there yet she has no French. I believe this is because of poor reference panels for these populations. The 5 highest countries using AncestryDNA are: The United States, Canada, the United Kingdom, Australia, and New Zealand. All of those countries (except the UK for obvious reasons) experienced migrations from the british isles throughout the 17th, 18th, 19th, and even 20th centuries. Thus the british isles reference panel is very strong. I am curious on what you guys think and your experiences.
