It's a bit difficult to draw conclusions about a species who has only four members we've actually seen on-screen in such a way as to be sure they weren't art errors. For what it's worth, the way that Twilight became an alicorn suggests strongly that they are not a 'tribe' like the other four (I'm including Changelings in this) but are magical mutations created by a very specific set of circumstances.

It wouldn't surprise me if the foals of alicorns are of their pre-ascention species or if they are completely sterile because of the magical mutations.
