In his Senior Thesis, Samuel Coskey answered the question of which axioms of $ZFC$ hold at each stage of the cumulative hierarchy. Here is the list of his results:
Axioms that always hold: Extensionality, Foundation, Union, Axiom Schema of Separation, Choice.
Axioms that hold in $V_{\alpha}$ iff $\alpha$$\gt$0: Empty Set.
Axioms that hold in $V_{\alpha}$ iff $\alpha$$\gt$$\omega$: Infinity.
Axioms that hold at limit ordinals: Power Set, Pairing.
Axioms that hold at inaccessible cardinals: Axiom Schema of Replacement.
My question is simply this:
What changes (if anything) in these results if Choice is dropped?
