Seems that 0+ is the most common blood group here, followed by B+. I never suspected that A+ is almost as rare as AB+. Interesting poll!
In the Western World alone the results would be different. It is only in Asia that B is very high. Distribution of the B type blood allele in native populations of the world More here: Distribution of Blood Types
I don't think everybody would know their blood groups but still most of the people know, as I do.. Mine is A+....
Yes i know it and my blood group is the AB+ and i like it because i am universal acceptor and can able to accept any type of blood group by me.
