There Is No Race...?

There is no race, except when we need to identify Elizabeth Warren as a Native American. In such cases we find that we can find "African" and "European" genes.

If there is "no such thing as biological race" then how did this highly distinguished geneticist managed to isolate chromosomes by "race"? That should be totally impossible. And think that's ONE [1] chromosome. Who knows what could be found on the other 22.

And what is this thing called "admixed individuals"? I thought one drop meant you were fully "not white"?

This is sooooooo confusing!
