Reply to Squeakbox's mixed-race question:

As for the terminology for those with two or more genetic heritages - I've not found or thought of something suitable. I had thought of extension - so Marley would be African-European-Jamaican. Since you can only be born in one place as long as its understood the last term is country of birth then people will naturally understand the rest. Obviously we may end up with descriptors containing four genetic heritages since we all have four grandparents. We would have to use continent descriptors for the genetic heritage part: Africa, Asia, Australia, Europe, North America, and South America (and whatever else people feel needs to added).
