I was looking for the post to quote saying that Rh- mothers reject the Rh+ fetus as if it was another species. That isn't true. Look at the mule or hiney - it is a distinct species that is born to either a donkey or a horse and it is not rejected by the mother. It just can't reproduce.
Also, I can't blood from anyone but O types. My body will react to the antigens and reject it and I might well die. I am, for all intents and purposes, allergic to all other blood types because I lack the antibodies against the antigens they carry, much like Rh incompatibility. The only difference is that there's no rejection in pregnancy.
Quoting: Anonymous Coward 12100946 When you say, "I can't blood from anyone but O types" you are still at a better advantage, because I cannot even get blood from people with the same blood type as me unless they too are Rh negative.
You are saying that Rh- mothers do not reject Rh+ babies? Surely you know they do...right? (don't call you Shirley?)

You have the correct information conceived in the wrong way. We are not saying that an Rh negative woman is likened to a female horse giving birth to a mule, or like a female donkey giving birth to a hinny. We are saying that an Rh negative mother IS the mule or the hinny trying to give birth where the other genes come from a horse or donkey. (An Rh pos. person as the partner in reproduction)
You said "cannot reproduce", well that's the entire point here. Rh negative mothers CAN reproduce an Rh+ child ONCE, and the only reason is that the Rh negative mother's immune system isn't fast enough to become Rh sensitized in the time it takes to have one child. The second time around, with no Rhogam, the mother cannot reproduce - is what we are saying.
So you're right, but in the wrong way.
