I can see how Rh- is only compatible with Rh- but how is Rh+ compatible with Rh-?
It should be that because O+ blood(which is my blood type) has all antibodies but no antigens that all other blood types including O- would be incompatible making O not a universal donor.
Also if O is the universal donor it should be O+ that is the universal donor and O- that isn't because Rh+ is compatible with Rh+ and Rh-, not just Rh+ or Rh-.
It should also be that because AB- has all antigens and no antibodies that AB is not the universal recipient.
I can see how A is not compatible with B and vice versa but for blood groups how is O compatible with all blood types yet people with O blood can only recieve O blood?
Also how is AB not compatible with all other blood groups yet can recieve all blood groups so that AB+ is the universal recipient?
Here is what I would expect from blood group mixtures:
O-A: A clumping in O
O-B: B clumping in O
O-AB: AB clumping in O
and that being true for the reverse order as well
AB-A: AB clumping in A
AB-B: AB clumping in B
as well as the one that everybody knows which is A-B: A clumping in B and B clumping in A
I would also expect for Rh compatibility:
Rh- with Rh+: Rh- clumping in Rh+
How is all this except for the A-B compatibility wrong, especially the O being able to only receive O yet A, B, and AB can recieve O as well as other compatible blood groups.
