Respuesta :
A mother who is blood group O can only pass an O allele to her son or daughter. A father who is blood group AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood group A (O from mother and A from father) or blood type B (O from mother and B from father).
What is blood type ?
The presence or absence of antibodies and inherited antigenic substances on the surface of red blood cells determines blood group . counting on the blood group system, these antigens are often proteins, carbohydrates, glycoproteins, or glycolipids.
Blood types are determined by the presence or absence of specific antigens, which are substances that, if foreign to the body, can cause an immune reaction . Because certain antigens can cause a patient's system to attack transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.
Your blood group is a classification of the antigens in your blood, including the Rhesus, or Rh, factor.
