Yeah there's no way to put it sensitively. Go here for a blood type calculator: http://www.biology.arizona.edu/Human_Bio/problem_sets/blood_types/btcalcA_popup.html. Basically if your mom is O and you are A then you father would have to be A or AB. With one parent as O and another parent as A their child would either be B or O, not A.

Is not possible. That just means u r adopted or u r a child that either belong to other relatives or someone of your parents. From what i learn in biology, if u father's blood type is B its actually OB, meaning B is a dominant characteristic in your father's blood, meanwhile your mother's is OO, O blood type is always recessive to 3 other blood types that is A, AB and B. So when test-cross is being carried out,possible combinations of characteristics that u might have are either O like your mother or B like your father. Not A or AB ( it's possible 2 have blood type A rh+ perhapz but any other letters in the alphabet are not likely )
-
B or O is what you would be.

Get a paternity test, and you'll know for sure.

are both you parent's blood types positive or is one negative. If both have positive or negative blood types it's possible but if one has positive and one has negative this is not possible; my mom's a doctor so I know.
