10 Mind-Blowing Blood Type Secrets Your DNA Doesn't Want You to Know

9. Blood Types And Ethnicity

There are links between blood types and ethnicity. Every ethnicity can have all of the major blood types in it. As a reminder, the major types are positive and negative O, A, B, and AB blood. It is worth noting that certain blood types are found more often in certain ethnicities. Type O blood is the most common worldwide. However, it is the most common among individuals with Hispanic heritage. Reports indicate that type O blood is found at a rate of fifty-seven percent in these individuals. Another example of the link between ethnicity and blood type is that type B blood appears to be the most common among individuals with Asian heritage. Finally, research indicates that there can be a lower risk of reactions when individuals receive blood from someone of the same ethnicity. It can also be of significant benefit as well. A prime example of this is the Ro subtype. This subtype is more common in black individuals and, as mentioned, appears to be a significant help in treating sickle cell anemia, which is also more prevalent in these individuals.
