I've heard various remarks/comments/ideas that incubation temperatures can effect/alter what is considered the holotype for a given subspecies of milk snake. I've tried hunting up articles on the subject but with little result... so what's the opinions/experiences of those of you with years of breeding experience behind you on the subject?

The included photo illustrating this point is one of my sons recent hatchling Black Milks... disregarding the obvious stripping I'm more curious about the white spot just above the nasal band. I've noticed this spot often on milks with an aberrant pattern. The spot is not typical for any of the subspecies of milks shown in Williams book, so... enlighten me if you will... do higher or lower incubation temps allow for such things?
