Best Answer: Your genotype determines your blood type before your born. There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO.h is not passed down from parents. With your parents having AB and O, you can only have type A or type B blood because O is recessive. You could have type O if your mother was AO or BO, but she isn't. Since you have type A, your blood is AO (A from your mother and O from your father... but A is dominant).
