if animals with the genotypes Aa AND Aa were mated....and they produce and offspring that has the genotype...aa....what principle is this??

recessive-ness?

Use the punnet square thing.
A a
A Aa Aa
a Aa aa

Remember the lower-case letter is always representing the recessive gene.
I would say that the principle is recessive.
