Sorry, but your arithmetic still doesn’t compute. No person can be one-third of anything.
Specifically, your ethnic proportions are always going to be fractions whose denominators are powers of the number two. So you can be 1/2, 1/4, 3/16, 9/32 Latino, etc. But there’s no way you can be 1/3 Latino.
Well, clearly.....not all of us are the genius you are in deciphering the human genome.
