I remember reading somewhere that blood can have more than just the regular ABO antigens. I wonder how that plays into that gene theory.
- alextheparrot 10y agoSome micropopulations have developed their own, unique, blood signatures (Bombay group is a good example here, they lack the H antigen that makes them universal donors but Bombay only acceptors). Blood types in general are super complex combinatorially. The concept of hybrid vigor (Expressing two different alleles expressed may yield a competitive advantage over expressing a single allele twice) has always interested me in regards to blood, though I haven't gone digging for a basis for that being a driving force.

And organ transplantation has demanded an even greater understanding of tissue compatibility than blood transfusions.
- logfromblammo 10y agoThe main 8 ABO+RhD types are encoded by just 2 genes. But there are about 200 rare blood types that arise from interactions with another 49 genes. Those 51 genes can express 379 blood antigens.
