Interesting, are all the following true?

1. The two jester types, banana and white smoke/coral glow all have dark spots.

2. Looks like at least one of the jester's is not a dominant type as mentioned breeding back to daughters to prove so assume the daughters are all normal (guess it would depend on how many produced, maybe just missed).

3. Banana and white smoke/coral glow seem to be some sort of dominant (can't remember now if I've even heard this detail about the white smoke/coral glow).

Can anyone think of an example of alleles where one mutations of a gene is dominant to normal and another mutation of the same gene is recessive to normal? Suppose that could happen but different inheritance would make me wonder if they are totally different genes that just happen to look similar (maybe chemically similar somehow).
