It depends.  In some cases, the research we used to develop the predictive algorithms were based on certain reference populations which may not be representative of the global population.  

Much of the genetic research currently available is based on studies involving people of European ancestry - so for some traits the data may be more accurate for people with this background.

HumanCode believes genetic testing should be available to all individuals globally, and is interested in supporting efforts to make DNA sequencing available to the broadest possible audience.  This includes supporting research efforts involving more diverse populations.
