"AA" can represent very many things:
Alcoholics Anonymous, American Airlines, Automobile Association, are just some examples. In some cases a temperature is relevant in others temperance! Without knowing which AA you mean, it is not possible to answer the question.

If ALL offspring are Aa, The parents are AA and aa.
Recorder: For One And AllAA BB AA GG AA BB A B A AA BB AA GG AA BB A B A BB BB AA G G BB B A A G A BB BB AA G G BB B A A G A AA BB AA GG AA BB A B A AA BB AA GG AA BB A B A
Here are the four possibilities: AA Aa Aa aa Therefore there is a 25% chance of producing a homozygous dominant offspring (AA).
If the parents are both AA, which results in the cross AA X AA, then the offspring will all be AA. If both parents are AA, resulting in the cross AA X AA, then all offspring will be AA. If BOTH parents are Aa, resulting in the cross Aa X Aa, then the offspring will be 25% AA, 50% Aa, and 25% AA. This is only true if the alleles are not sex-linked.
As per a Punnet Square: Aa crossed with aa can result in Aa, Aa, aa, or aa. So 50% heterozygotes, 50% recessives.
There are two choices that produce the least phenotypic variation. AA times aa produces only Aa offspring. AA times Aa produces and AA and Aa offspring.
