It was given a more specific answer in the recent Facebook Q&A, Humans and Faunus can interbreed, and the child will be human or faunus but not both. The simplified answer was actually;

human+human=human

faunus+faunus=faunus of either parents species

human+faunus= human or faunus of parent species

That is dumbed down massively though so it is likely faunus traits can be inherited from further back in the lineage rather than just the parents.
