A PF2 ancestry is the equivalent of an A5e heritage. A PF2 heritage otoh is the equivalent of an A5e culture.i mean, the difference there is "ancestral feat" is its own entire category of feat, and you get ancestral feats specifically (on top of whatever other feats you'd normally get, like class/skill/general/etc) at 1st level and every 4 levels thereafter (or even more commonly then that with the ancestral paragon variant rule). that, and you get a heritage (which is basically a subrace).
it has much more in common with a5e heritages, really (though it's still quite different from those).

The neat thing about heritages and cultures in A5e is that they can be mixed and matched. You could have a character of human heritage growing up in a dwarven culture.
