Thread: Blood Types!

Hello, i have a question for Science. It's about how if you donate a particular blood type to someone, they could die, and you know how, Type O is the universal thingo! Do you get what i mean!
Okay here is the question:

Which one of these donors and receivers would result in clotting? To answer, sketch in rough a grid for each, showing receiver and donor antigens and antibodies.

please tell me if the attachments worked!

oops, the choices that you had to select were these:

Receiver B; Donor B
Receiver A; Donor AB
Receiver A; Donor O
Receiver AB; Donor A

1..................Receiver..........Donor
....Antigen..........B..................B
....Antibody.........B.................B

2..................Receiver..........Donor
....Antigen..........A..................A&B
....Antibody.........A.................-

3..................Receiver..........Donor
....Antigen..........A..................-
....Antibody.........A.................A&B

4..................Receiver..........Donor
....Antigen..........A&B..............A
....Antibody.........-.................A



Case number 2 would result in clotting (receiver A and donor AB)
