What are the three blood types in the world population?
I believe your question is initially wrong. There are a total of 4 blood types: A, B, O and AB. Each of them can be Rh positive or negative which gives us 8 blood types: A+, A-, B+, B-, O+, O-, AB+, AB-. I hope this answers your question!

No, only 7% of the world has O negative blood type.We couldn't say our blood type a negative without testing.It has been found that the most common blood types are the Rhesus factor positive or all the positive blood types like A+, B+, AB+ and O+. When compared with their respective negative counterparts, the percentage of the positive blood types is more than that of the negative ones.
