I saw this on Ancestry‘s blog just now – Understanding Your New Ethnicity Estimate: https://blogs.ancestry.com/ancestry/2019/05/02/understanding-your-new-ethnicity-estimate/.
We’re always looking for new ways to help support our customers on their journeys of personal discovery. Often that means updating our products and services to take advantage of the most advanced science and technology.
Last fall, we introduced the capability to provide more precise ethnicity estimates to our customers using an algorithm that analyzes longer segments of genetic information. For some of our existing customers, this has meant that previous ethnicity estimates have evolved as a result of this new technology.
We recognize that an individual’s personal sense of identity is very important and that any journey of personal discovery may take turns that are surprising or unexpected. However, it is important to keep in mind that your DNA doesn’t change, but the science and technology behind understanding it constantly evolves and we endeavor to ensure that this cutting-edge science is reflected in our offerings.
Starting May 30, 2019, all AncestryDNA® customers will be transitioned to their new, more precise ethnicity estimate. If you received your AncestryDNA® results prior to September 2018 and wish to keep a record of your prior results, you may download them by July 20, 2019.
