I don't think we've yet seen a parent-child dynamic in RWBY at all so it is hard to imagine how we could say they have similar semblances.

It was on the same Livestream where they said humans and faunus could interbreed if I'm not wrong.

They didn't said "hereditary" per se, but they did say something along the lines of a parent's semblance having some influence in their children semblance.
