Question
Does a child always have the same blood type as his mother?
I only ask as my dad had a rare blood type and I wondered if I would inherit it or does the mothers, through sharing in the womb take, precedence
Answer
Blood type is determined by your genetic makeup. That comes from your mother and father. Being in your mothers womb has nothing to do with what type you are. You could have the same as one of your parents, or different from both. brbrThe blood quottypesquot are actually different molecules that get put on your particular red cells. There are A and B. You can have just A, just B, both A and B, or none of the molecules. brbrThe different blood types then arebrA, B, AB, O. brThen you can be Rh pos. or Rh neg. for any of those . Rh being another moleculebrbrThese make up the usual information that people hear about when they get their blood type. There are actually tons more different molecules on your blood cells that are tested for when getting a blood transfusion. But generally they are not discussed with patients because they are more esoteric items.brbrIf you know what your father and mother are, you could figure out the possible types you can be. But without the information, I cant be more specific.
