2. brother x sister, both aurora, produced all aurora babies. How many?
3. son (aurora) x mother produced dead embryos.

If this information is wrong, please correct it.

The second mating inclines me toward the belief that aurora is a recessive mutant gene. But it could have been the luck of the draw so does not rule out the chance that aurora is a dominant or codominant mutant gene.

Outbreeding to an unrelated snake is the only way to tell which it is. If a dominant or codominant mutant gene, then aurora x normal would be expected to produce 1/2 aurora and 1/2 normal. If a recessive mutant gene, then none of the babies would be expected to be aurora.

Good luck to you and the guys at Mad Men Morphs.
They would be considered dominant according to the first breeding. To an unrelated male. 7 babies. 6 auroras.
