Homework Answers
Answer: True
Explanation:
A blood group contains A antigen.
B blood group contains B antigen.
AB blood group contains A and B antigens = Universal acceptor
O blood group does not contain any antigen = Universal donor
These antigens are located on the
RBC surface.
These blood group antigens do not exhibit
cross-compatibility.
When B blood group is injected into a person with A blood group,
antibodies are produced against the B antigen.
Add Answer to:
t/f

antigens is stimulated be exposure to...

Rh is the most complex of the blood group types, involving at least 45 different antigens. The most clinically important antigen, D or RhO, is encoded by the gene RhD which is found on chromosome 1. Individuals that are Rh-positive have either one or two RhD genes, whereas the Rh-negative phenotype is caused by the absence of the RhD gene. (The antithetical allele d does not exist, however the letter "d" is used to indicate the D-negative phenotype). For the...
