-
ABO Pheno type is A
What are the possible genotypes
AA, AB, A1A1, A1A2, A2A2, A1O, A2O
-
ABO Pheno type is B
What are the possible genotypes
BB or BO
-
ABO Pheno type is AB
What are the possible genotypes
AB, A1B, A2B
-
ABO Pheno type is O
What are the possible genotypes
OO
-
In order from greates to least, give those phoenotypes that have the H antigen on their red cells
O, A2, B, A2B, A1, A1B
-
Which reacts with A1 Lectin?
A1 or A2
Positive agglutination occurs with A1
-
What causes a weakend D antigen?
- Weak D: RHD mutations. All proteins are present, but antigens are reduced.
- Partial D: Not all epitopes are presnt.
- C in trans to RhD: The allele carrying C(r') is present in trans to (R0r')
-
What 2 genes are at the Rh genetic locus on Chromosome 1
RHD & RHCE
-
RhAG glycoprotien does NOT express Rh antigens.
just a fact
-
A haplotype that produces both c & e (R0) also produce what antigen & why
A haplotype the produces both c & e also produce f. The 3 separate antigens is encoded by a single gene (haplotype).
-
A person who inherits R1 & R0 will have the c & e antignes on their red cells will not produce what antigen and why?
c & e are on different genes, so they are unable to produce the f antigen
