What are 3 examples of ethnic boundaries? : )

i believe that your talking about culture apportion if not i'm sorry but if you are ill give you some examples.

1. A white person trying to be black like darking their skin color and getting hair styles that are for black people like dreads and cornrows.

2. people that are trying to be Korean and Japaneses like whiting their skin color and trying to change the shape of their faces and the use products to make them look Japanese when they are not.

I believe that you got an idea from the 2 examples i just gave you how about you come up with the 3rd example. Again i'm really sorry if ur not talking about culture apportion.
