Crested gecko genetics are very different from your typical recessive, dominant or co-dominant lines as seen in corn snakes and ball pythons. I believe crested geckos are generally called polymorphic...basically you can get quite a range of patterns and colors from the same parents, even traits that wouldn't be expected from the past several generations of parents.

Selective breeding can ensure certain patterns and colors...but how these all work I don't know off hand. Best way to get great looking offspring is to find adults that have the traits you are looking for and breed them together. Checking out the top crested gecko breeders and their work in the past, will also be a great way to understand how various traits are passed.
