US race law: if you had any black ancestors ever, you're black (one-drop rule)

also US race law: not native unless you have X% native ancestry though (blood quantum)
There's nothing scientific about this. It just really worked out for white landowners for there to be as many black folks & as few natives as possible. So that's how they wrote the laws.
Yes I got interrupted before putting in the *asterisk on the one-drop rule "only" being a state law ... that was very popular and stayed in force until less than 50 years ago. Congrats, pedants, you've outdone yourselves
