He looks like the het Hypo is just showing thru some and lighting him up alittle.
If both of the Mojaves are from the same clutch then they would both be 100% Het.
Also, if they are both hets having the Pastel male in there, even just to get the male Mojave going, is a bad idea. He may sneak a lock or 2 in without you even witnessing it. You won't be able to tell which male fathered the clutch and therefore not know what % het the offspring are. Except, if you get Super Mojaves(66% Het) or Pastaves, Pastels(50% Het). All the other offspring would have to be classified as 50% hets even if they may be 66% het.
