What would be the possible genetically different gametes for AABb genotype

Can someone answer this question in this forum 

 

How far have you got with trying to answer it yourself?

Post your thought process and I might be able to give you some pointers.

@Dord I think the possible gametes would be AB AB Ab Ab so these are four gametes formed and 2 genetically different is this answer right?What you think

Going backwards in the Punnett square, taking into account possible restrictions on the parental generation (wild types, homo-/hetero-zygotes, etc.)

I think, it is not too complicated to work here. Thanks for answers
