Distribution of Blood Types


Modern Human Variation: Distribution of Blood Types: "Blood provides an ideal opportunity for the study of human variation without cultural prejudice. It can be easily classified for many different genetically inherited blood typing systems. Also significant is the fact that we rarely take blood types into consideration in selecting mates. In addition, few people know their own type today and no one did a century ago. As a result, differences in blood type frequencies around the world are most likely due to other factors than social discrimination."
