The team of scientists at AncestryDNA have increased the company’s reference panel to more than double its previous size with DNA samples from more places around the world, resulting in the latest update to AncestryDNA ethnicity estimates. In short, with more detailed data to work with today, the company can now provide more accurate locations of your ancestors. This means there may be some changes to the results you received earlier.
The expanded AncestryDNA reference panel helps deliver even more precise regions in West Africa, northwestern Europe, the Americas, Oceania, and Southeast Asia.
Quoting from the announcement in the AncestryDNA Blog:
“For example, previously we had North and South America as two large regions: Native American–Andean and Native American–North, Central, South. With this new update, we are able to refine the areas into 11 smaller ones. If you received one of the older regions before, your new report will most likely have one of the newer, more precise regions instead like Indigenous Eastern South America, Indigenous Cuba, and Indigenous Americas–Mexico, among others.
“While not common, some customers may also lose a small percentage region as a result of this update.”
