Questions and Answers

What is the main reason why blood type must be matched correctly during donations?

To increase the chances of a successful transfusion

To enhance the blood's oxygen-carrying capacity

To ensure compatibility with the immune system (correct)

To prevent clotting

What is unique about type O blood?

It can only be received by individuals with type O blood

It has neither A nor B antigens, but can only be received by type AB individuals

It can be donated to anyone (correct)

It has both A and B antigens

Why can individuals with type AB blood receive blood from anyone?

Because they lack A and B antigens

Because their immune system is weaker

Because they have both A and B antigens (correct)

Because they are universal donors

Study Notes

Blood type is a phenotype that cannot be determined by physical appearance, unlike other phenotypes such as eye color, hair texture, and height.
Blood is composed of platelets, plasma, and red blood cells, and each has proteins on its surface.
The immune system is very protective and will attack red blood cells with proteins it is not used to, which is why blood type must be matched correctly during donations.
There are four main blood types: A, B, AB, and O, which are determined by the presence or absence of specific antigens on the surface of red blood cells.
Type A blood has A antigens, type B blood has B antigens, type AB blood has both A and B antigens, and type O blood has neither A nor B antigens.
A person with type B blood can accept type B blood but not type A or AB blood, as their immune system will attack the unfamiliar antigens.
Type O blood can be donated to anyone, but individuals with type O blood can only receive blood from other type O individuals.
Individuals with type AB blood can receive blood from anyone, as they have both A and B antigens and can recognize all types.
Blood types also have a plus or minus sign indicating the presence or absence of the Rh factor protein on the surface of red blood cells.
Blood type is genetically inherited and is a great example of multiple alleles, with alleles being different forms of a gene.
A couple with type A blood can have a baby with type O blood if they are both heterozygous for the A allele, but a baby with type B blood is not possible.
Punnett squares can be used to determine the possible genotypes and phenotypes of offspring in blood type inheritance problems.
