Best Answer

It is possible to be AA, AO, OO, BB, BO, The type of blood is the presence of a part.
AA and AO will both test as A.
If you consider the presence of the rh factor it can add RR, Rr, rr.
Parents who are both AA will all have children that are A.
Parents that are AO or BO can have children either A, B, AB, or O

What genes are a good example of multiple alleles?

The human ABO blood group system is a good example of multiple alleles. There are three alleles involved: IA, IB and IO. If a person inherits two IA alleles, or IA and IO, they will be group A.
