One sister was listed as greater than 60% from English ancestry. The other had no English ancestry listed. Test error? Both have same mother and from appearances same father.
As someone trained in medical field, I would expect better results.
Sounds like really sloppy something. I don’t think much of 23andme or ancestry.com. FTDNA.COM has much greater respect in the field. There’s also the National Geographic Genographic 2.0 option, too. Though, certainly the Nat Geo is full bore Oligarchy from its founding on.
that is more common than one would think.
decent explanation here:

and that’s why having Warren take a DNA for Native American might be useless.
