He is being bred back to his het orange hypo mom. She and some of his siblings are banded as well, and I'm interested in seeing what happens with that pattern. I'm also breeding him to a lemon pastel poss het orange hypo. The normal and pastel babies that result from those pairings will be het for either orange or green hypo, but we wouldn't know which. Any hypos that hatch would have a 50% chance of being either orange/orange or orange/green. I think there would be a difference in the coloration of the hypos, though I can't say if I would be able to tell the difference in any pastel hypos (assuming my lemon pastel poss het proves out). And yes, some green hypos are compatible with orange hypos.
I'll definitely keep you in mind if any babies hatch, Jessi!
