What an interesting match-up! A lot of different outcomes are possible... based on the assumption that the Nova only has 1 copy of Enigma allele, and the Phantom only 1 copy of TUG Snow* and Hypo, this is what you can expect:
*If the Phantom happens to have 2 copies of TUG Snow allele, you could expect all the babies to be TUG Snows of some sort or another.
