3. ABO Blood Group NOTE: A and B are codominant Three alleles A, B, O
or IA, IB, i
Phenotypes of Blood types: A B AB O
NOTE:
A and B are codominant

4. Drop of Blood Red blood cells have antigens Plasma has antibodies
Don’t mix same letter antigens with antibodies

7. Antigens on RBC
antigens
antibodies

8. Antigens on surface Rh A

9. B antigens on surface Rh B

10. Both A and B antigens on surfaceRh

13. Alleles and antibodies

16. Official Blood Test Card

18. Blood Typing Simulation
A sera is colored blue

Rh sera is colorless

19. ABO Blood Type
ABO Blood Typing

20. Type A + A Rh B

21. Type B Pos A Rh B

22. Type AB+ A Rh B

23. Type O neg. A Rh B

24. Rh+ and Rh- dominant Rh positive gene (+) produces the Rh antigen
recessive Rh negative gene (-) does not produce an antigen

25. Rh+/Rh+
Rh+/Rh Rh+
Rh-/Rh- = Rh-

26. (DD) or (Dd) = Rh+ (dd) = Rh- (they do not have the key Rh antigens).

27. Rh + or - ?
Anti-Rh
antibodies .

28. O positive and negative blood

30. Donating Blood

31. Best Blood
If you include the Rh factor, then the universal donor becomes O Negative while the universal recipient becomes AB Positive.

32. Percentages in U.S. O Positive 38.4% A Positive 32.3% B Positive 09.4%
O Negative 07.7%
A Negative 06.5%
AB Positive 03.2%
B Negative 01.7%
AB Negative 00.7%
