Blood Types Lab Quiz

review lab, notes, and practice worksheet on punnet squares

what type of dominance determines blood type?

codominance and simple dominance (2 codominant alleles, 1 recessive allele)

what letter represents the blood type gene?

I

what are the 4 basic blood types?

A, B, AB, and O

genotype of type A blood

I^AI^A or I^Ai

genotype of type B blood

I^BI^B or I^Bi

genotype of type AB blood

I^AI^B

genotype of type O blood

ii

antigen

proteins on the surface of the cell that help identify the cell (act as ID tags); determines blood type of an individual

antibody

proteins that surround blood cells to protect them against foreign antigens

why is it important to know blood type when doing transfusion?

giving someone the wrong blood type can be fatal

antiserum

antibodies capable of causing agglutination and identifying blood type

agglutination

the clumping of cells

Rh factor

a protein antigen found on the surface of red blood cells

what kind of dominance is Rh factor?

simple dominance (positive is dominant, negative is recessive)

what letter represents Rh factor?

R

what determines whether a blood type is positive/negative?

the presence of Rh makes a blood type positive, and vice versa

what antigens/antibodies does the A- blood type have?

A antigens; Anti-B and Anti-Rh antibodies

what antigens/antibodies does the A+ blood type have?

A and Rh antigens; Anti-B antibodies

what antigens/antibodies does the B- blood type have?

B antigens; Anti-A and Anti-Rh antibodies

what antigens/antibodies does the B+ blood type have?

B and Rh antigens; Anti-A antibodies

what antigens/antibodies does the AB- blood type have?

A and B antigens; Anti-Rh antibodies

what antigens/antibodies does the AB+ blood type have?

A, B, and Rh antigens; no antibodies

what antigens/antibodies does the O- blood type have?

no antigens; Anti-B, Anti-A, and Anti-Rh antibodies

what antigens/antibodies does the O+ blood type have?

Rh antigens; Anti-B and Anti-A antibodies

what blood type is the universal donor and why?

O-, because it has no antigens that can be attacked

what blood type is the universal receiver/recipient and why?

AB+, because it has no antibodies to protect the cell from any antigens
