First off, there is the possibility that interbreeding is not possible.

If it turns out to be possible, as in, the species are close enough to each other to allow producing offspring, then I think the baby's looks would be decided on a similar way to the looks of the baby of two people from different ethnics. Some genes will show dominance over others and that should determine if the kid gets and extra pair of ears or horns of night vision. I would think evolution would make traits that are advantageous for survival like the mentioned night vision be dominant.
