Sorry if this sounds silly.

Can all types of races of people have all the different blood types and be positive or negative rhesus? Or do some races not have certain ones?

I remember my dad saying that O blood type is very common among East Asians. However, I think there still are other blood types. However, I always thought that O was common among most ppl, regardless of their race...

Race is really a cultural construct. Genetically the differences between the different "races" are so minuscule as to be meaningless. So to answer your question, that would mean that all races can have all the different blood types as well as + and - rhesus.

: It has been proven that there is much more biodiversity within a group than between groups. I'm African American. My mother who is of Native American, African, European, and Indian descent is A positive. My father who is Nigerian is B positive. I'm AB positive. My husband is white. His mother is Hungarian and Polish and is A negative. His father is Polish and Croatian and B positive. DH is AB positive. Our son is also AB positive. So "race" or region of ethnic origin has nothing to do with blood type. We're all human beings otherwise we wouldn't be able to reproduce with each other.

There are differences and tendencies among different people from different parts of the world. I learned about it in my Biology class.



About halfway down this page, read "Blood Groups Differ Around the World"
http://www.ncbi.nlm.nih.gov/bookshel...tigen&part=ch2

The distribution of the four ABO blood types, A, B, AB, and O, varies in populations throughout the world, therefore certain populations of people have a greater % of a certain blood type. . . however,

Quote:
These patterns of ABO and Diego blood type distributions are not similar to those for skin color or other so-called "racial" traits. The implication is that the specific causes responsible for the distribution of human blood types have been different than those for other traits that have been commonly employed to categorize people into "races."

Also, this website has some good maps at the bottom.

Here's a fun tool if you know either (a) one parent and the child's blood type or (b) both parents' blood types.

There are tendencies but in a bizarre coincidence, my MIL and I have the same blood type, though we were born literally halfway around the globe (12 hours difference). There is so much mixing that anyway, you have to check. Most all races, like Marylizah said, have all blood types, though some are more common than others.

It's not that the stay-at-home-parent gets to stay home with the kids. The kids get to stay home with a parent. Lucky Mom to DD1 (4 y) and DD2 (18 mo), Wife to Mercenary Dad
