If I recall, he's not the only Canadian member that lives where most of the snakes are very red flames but we haven't heard from the other guy in a very long time. Anyway, to answer your question, it's not a dominant gene. It's polymorphism. It will vary in a single litter or population. You can line breed over generations to select for the orange color though, just as nature selects for color sometimes if there is a local advantage to certain colors.
