Thanks Rich for posting a link to the history of Ashy/Cinder.
I have seen Het Cinders that were quite obviously "Het Cinder", based on some of the markers described above, and some that were much more subtly Het Cinder. IMO, the markers for Het Cinder can be masked by the presence of other mutations (e.g., Sunkissed, Motley, etc...). This is certainly true for some other mutations. Buf for example, is dominant, but so variable at times I can hardly tell which hatchlings are displaying the phenotype. I don't think we should discount the possibility that Cinder is perhaps incomplete dominant because it does not consistently "shine through" when combined with other mutations. Hopefully some additional folks out there who have worked with Cinder, perhaps not in combo with too many other mutations, will chime-in
