Why are my Ancestry and 23andMe results different?
As each company has its own reference groups then the ethnicity for an individual will reflect those differences. If you upload your raw data to other companies, you will see changes in your ethnicity. Percentages are likely to stay roughly accurate at the continental level, but regions are somewhat fluid.7 May 2020

Does 1% DNA mean?
As our DNA halves through generations, 1% of that ethnicity likely entered your bloodline 7 generations ago. This means that it would have been one of your great, great, great, great, great grandparents that brought this ethnicity into your bloodline.
What does 2 percent DNA mean?
For example, if you find 2% Indigenous Americas DNA on Ancestry, and build your tree back a few generations and find that you have ancestry going back hundreds of years in what is now Arizona, you might have found the branch of your tree with the source of your Native American DNA.24 Sept 2021

Why you shouldn't do a DNA test?
The results are often inaccurate. In plain English, that means testing companies often mistook a harmless genetic mutation for a dangerous one. Such false alarms could cause patients significant stress and force them to undergo expensive, unnecessary, testing or procedures.20 Nov 2018
