DNA for identification of perpetrators and relatives is science.
Using DNA to say you are 0.13% Polynesian is not.
I agree, but they can say that you are a 0.13% profile match to Polynesian, with a standard error of +12%/-0.13%. It’s leaving out the estimation error, and lack of a rigorous definition of what that 0.13% (or whatever) means that makes it “junk”.
