Dear sir most respectfully
My name is Anwaruddin Himmat
I am not that much able to define my question in English but I will try
my question is about blood group transcription
we know O group has antibody and doesn't have antigen and A group has also antigen and antibody
if we give O group blood to that person who has A group blood
in this case why O group antibody doesn't reaction against of A antigen
Kindly answer me Thank You
