Colombian Blood Type


I was recently reading the book 1491, by Charles Mann. As I read, I came across the mention of a genetic bottleneck that had occurred among the Native American Indians. One of the examples given in support of this genetic bottleneck idea was that there is a predominance of type O+ blood among people of the Americas. Intrigued, I checked my family's blood type and indeed, they are all O+. Hmmm.



While in Colombia, on July 20th, we participated in a Blood Drive that was held at our local church. When I told the workers my unusual blood type, they were pretty shocked. According to them, they had never seen anyone with my blood type. It kind of worried me. I hope that I never need a blood transfusion in Colombia.

Do you have O+ blood? Are you Colombian?

I am not Colombian but my husband is and both of us have O+. I'm pretty sure that guarantees that all of our kids will have it too.

Interesting. We're Colombian and my whole family is A+. Are you O+? I know it's the most common in most parts of the world including Colombia.

My whole family is from Colombia too, we all have type A+ blood. Would this suggest European admixture?

Hmmm my wife was adopted from Colombia and she is B+. Must be a rarity in that region. Maybe that would help her to locate her family...
