Question:

DNA, has any one done it , found out what their grandparents race are?

Best Answer - Chosen by Asker: The girl below was partially correct, race is a culturally-derived construct and does not truly exist, however ANCESTRY is genetic and can be determined through DNA analysis. So, it is possible to not only infer your major ancestry (which you probably already know) but your ancestral proportions (which, you probably do not know) through genetic testing.

Here are a few websites that explain in much better detail:
