I hope I don't need to let you guys know I'm being sarcastic but I'm going to let you know just in case.. should I assume everybody knows I'm sarcastic in the future, seems like the place that I could safely assume that?
This is funny but how on earth could a DNA test check how "Mexican" you are? Surely that's a legal notion and not a DNA thing.
I mean, say a Chinese person in the Gold Rush went down to Mexican California, stayed long enough to effectively be a resident, and then went up the States, it's not like he'd aquire a little passport stamp on his mitochondria.
