The question does not specify any particular country or race. Warrior's answer is for the United States. The world wide situation is covered by this site: http://anthro.palomar.edu/vary/vary_3.htm Nov 19 07, 2:50 AM

The answer varies greatly from country to country. For example -- South Korea and China average about 27 percent on B+ against the U.S. average of 9 percent. Conversely, Hong Kong comes in at <0.3% on B- compared to 2% in the U.S. Nice chart follows at: http://en.wikipedia.org/wiki/Blood_types Nov 19 07, 10:39 AM
