Front

Which blood type is known as the universal donor?

Back

Blood type O is known as the universal donor because it can be given to any other blood type.

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.

Front

What are antibodies?

Back

Antibodies are proteins produced by the immune system that can recognize and neutralize foreign substances, including antigens.

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 inheritance pattern allows for blood type AB?

Back

Blood type AB is possible due to codominance, where both A and B alleles are expressed.

Front

If a father has blood type AA and a mother has blood type AB, what are the possible blood types for their children?

Back

The possible blood types for their children are A (from AA) and AB (from AB), with a 50% probability for each.

Front

What is the significance of blood type compatibility in transfusions?

Back

Blood type compatibility is crucial in transfusions to prevent immune reactions that can occur if incompatible blood types are mixed.

Front

What is the role of plasma in blood?

Back

Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products throughout the body.
