Title: Genetics - rhesus blood groups
Post by: rubypippen on October 12, 2017, 06:52:45 pm

Does anyone know how many alleles there are to determine rhesus blood groups - I've had different sources tell me 2, 3 and 6 and I don't know which one is correct ???

I believe for rhesus groups there's mostly just Rh- and Rh+ (on antigen D). Of course, this is paired with blood groups: A, AB, B and O. I think the answer you need is just 2, because we tend to discuss inheritance of Rh+ or Rh- over any other.
