  1. When I learned blood type, my teacher used immune system to explain. For an example, blood type A which is antigen A, then its antibody is anti B. If it is antigen B, then its antibody is anti A. WHY? why if antigen A,then it’s antibody B? I don’t get it according to the immune system?
  2. Genes are in DNA or DNA is in Genes?
  Hope you can tell me, thanks.

  genes are made out of DNA.
  antibodies are made to attack antigen different from the hosts. Antigen A host would make antibodies to attack antigen B, because it’s foreign.
