This question was asked me during a recent blood drive here. In the U.S. the frequency for various blood types is O = 46%, A= 42%, B = 9%, AB=3% However in Japan, I know that Type B is actually in the majority. Does anyone have the exact figures, not just on the U.S. and Japan, but worldwide by race. Mail me, or if you decide to post, post only to net.med (not both .med and .sci - to avoid duplication.) -- Craig Werner !philabs!aecom!werner What do you expect? Watermelons are out of season!

Blood type distribution is often used as an indicator of ancient
migration paths, in the same way as are the relationships among
languages (glottochronology).

I don't know the exact statistics, but you will find that in all European countries, and those settled by European countries, that type B blood is very rare. I heard an explaination of this is that people with type B blood are more likely to die if they catch bubonic plague. The plague in the middle ages killed off most of the people with B blood. In other areas of the world where the plague did not reach, you find about 50/50 A and B type blood. Jon Biggar {allegra,burdvax,cbosgd,hplabs,ihnp4,sdccsu3}!sdcrdcf!jonab
