What are blood types?

Back

Blood types are classifications of blood based on the presence or absence of specific antigens on the surface of red blood cells.

Front

What antigens are present in blood type A?

Back

Blood type A has antigen A on the surface of its red blood cells.

Front

What antigens are present in blood type B?

Back

Blood type B has antigen B on the surface of its red blood cells.

Front

What antigens are present in blood type AB?

Back

Blood type AB has both antigen A and antigen B on the surface of its red blood cells.

Front

What antigens are present in blood type O?

Back

Blood type O does not have antigen A or antigen B on the surface of its red blood cells.

Front

What is the universal donor blood type?

Back

The universal donor blood type is O, as it does not contain A or B antigens.

Front

What is the universal recipient blood type?

Back

The universal recipient blood type is AB, as it can receive blood from any type.

Front

What is codominance in genetics?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is the inheritance pattern for blood type AB?

Back

The inheritance pattern for blood type AB is codominance, where both A and B alleles are expressed.

Front

What are antigens?

Back

Antigens are proteins on the surface of red blood cells that determine blood type and can trigger an immune response.
