ACTIVITY 4: Multiple alleles and ABO blood groups Karl Landsteiner discovered the ABO blood groups in 1900. He found that glycoproteins called antigens A and B may be found on the surface of human red blood cells. People with type A antigens have blood type A; people with B antigens have blood type B, people with both A and B antigens have blood type AB and people with neither antigen have blood type O. These blood types are important because if a person receives a blood transfusion from someone who has red blood cells with foreign antigens, serious injury or death may result. A person with blood type AB may safely receive blood of which type(s)? ___ A person with blood type A may safely receive blood of which type(s)? __ A person with blood type O may safely receive blood of which type(s)?__

A person with blood type AB may safely receive blood of which type(s)? ___
A person with blood type A may safely receive blood of which type(s)? __
A person with blood type O may safely receive blood of which type(s)?__
The gene which controls ABO blood type has 3 alleles. Two of the alleles are co-dominant
(IA and IB), and the third is recessive (i).
What is the genotype of a person with type AB blood? ___
What are the possible genotypes of a person with A blood? ___
What about type B? ___
What about type O? ___
A. Do a Punnett square for a cross between a woman with blood type O and a man with type AB.
