Is the super pastel from crossing a NERD pastel with a Graziani pastel homozygous at one locus or heterozygous at two loci? In other words, does such a cross have two pastel mutant genes in one gene pair? Or does such a cross have two gene pairs, with one pair containing the NERD pastel mutant gene and a normal gene and the other gene pair containing the Graziani pastel mutant gene and a normal gene?

Has anyone crossed a NERD line lemon pastel with a Graziani line pastel, taken the super pastel babies, raised them, and mated them to normal ball pythons? If such matings produced only pastel babies, then the two pastel mutant genes are in one gene pair. If such matings produced some normal babies, then there are two gene pairs, and each of the two mutant genes is in a different gene pair.

I'd love to know whether this has been done or not.
