Question

Anti-N will react stronger with which phenotype?
A.M-N+
B.M+N+
C.M-N-
D.M+N-

Answer 1

Anti-N antibodies will react strongest with the M-N+ phenotype because it expresses the N antigen, leading to an antigen-antibody reaction.A.M-N+

Step-by-step explanation:

The student's question refers to the antigen-antibody reaction specific to blood phenotypes. Anti-N antibodies specifically react with the N antigen present on red blood cells. Therefore, the phenotype that would react the strongest to anti-N antibodies is M-N+, because it expresses the N antigen that anti-N can bind to, causing agglutination. In comparison, M-N-, although it has the M antigen, does not present the N antigen to which anti-N could react.
