So, you have a type A, which means one has A, you have a B, which means one has B

So right now, Parent A has a blood type of A, and Parent B has a blood type of B

Now a child has AB, which is a possibility figuring that A and B are options

Now that a child has O, which is only a possibility if both parents have O, the Genotype of your parents are AO and BO.

Hope this helped :)
