What is the significance of antigens in blood types?

Back

Antigens are substances that can trigger an immune response. In blood types, they determine compatibility for blood transfusions and organ transplants.

Front

What is the universal donor blood type?

Back

The universal donor blood type is O-, as it lacks A and B antigens, making it safe for transfusions to any blood type.

Front

What is the probability of offspring having type O blood if both parents are heterozygous for type A blood?

Back

25%.

Front

What antigens are present in blood type O?

Back

None.

Front

What is the difference between blood type A and blood type B?

Back

Blood type A has A antigens on the surface of RBCs, while blood type B has B antigens.

Front

What blood type is considered the universal recipient?

Back

AB+ is considered the universal recipient because it has both A and B antigens and can receive any blood type.

Front

What happens if a person with type A blood receives type B blood?

Back

The person's immune system may attack the B blood cells, leading to a transfusion reaction.

Front

What are the possible genotypes for blood type O?

Back

The genotype for blood type O is ii, where 'i' represents the O allele.

Front

How are blood types inherited?

Back

Blood types are inherited from parents through alleles. Each parent contributes one allele, determining the child's blood type.
