I'm not sure of any of the answers for your other questions but as far as the ratio goes...note that the clutch will not always be %50 normals 50% mojaves. The ratio is actually PER individual snake. For each individual hatchling, it has a 50% chance of being normal or a 50% chance of being mojave. You could get all normals, all mojaves, a 50-50 split or 1 mojave and the rest normals. You won't know till they hatch.
