Ok a poss dbl het would mean it is a normal looking animal and MIGHT carry the two genes stated, and if bred to a normal you would all normal looking babies that are what I have always heard as poss. poss dbl hets. Which means that if by chance the original poss. dbl het was in fact a dbl het then the babies might carry on or both of the genes.... In reality you would produce normals that could only be sold as normals because of the background of them.
