As I mentioned in my first response in this thread, it makes no difference whether we're talking about recessive, co-dom, or dominant. The genetics work the same. The only difference is the visual result.
So, if a het Axanthic x het Axanthic =
25% homozygous Axanthic
50% het Axanthic
25% Normal
then
Pastel (heterozygous) x Pastel (heterozyous) =
25% Super Pastel (homozygous)
50% Pastel (heterozygous)
25% Normal
or
Pastel (heterozygous) x Super Pastel (homozygous) =
50% Super Pastel (homozygous)
50% Pastel (heterozygous)
Look at travisjara's post above, showing the punnet squares for axanthics, and plug in Pastel for het axanthic, and Super Pastel for Axanthic. The results will be the same. Again, the only difference is visual expression. In other words, where he said that het axanthics look normal, heterozygous Pastels do NOT look normal. Therefore, there would be no "50% probable het Pastels".
