I'm not quite sure I understand your question.  Since the genome project, science has discarded the concept of "race" entirely.  There is only commonality of genetic markers.  For instance, I am a white male.  I have more in common genetically with a black male than I do with a white female. 
 
You might ask your question in the context of skin color, since that is just a genetic marker and since some people still put a non-proportional amount of importance to it.  But scientifically, there really is no such thing as "race".  There's not even a "human race", but a "human species". 
 
This is going to come as quite a shock to all the racial supremascists, once someone gets them to go to school and take science.
