The Prevalence of Duckbill and Popularity of Cinnamon

[OhhWatALoser]

This is the first time I have heard of this also, interesting. Besides super black pastels and super cinnys the only duck bills I have seen are on normals. About the only thing I would add to the single gene cinny/black pastels is they seem to show ringers more often than other morphs. Any other claims to this?

surely if you start with, lets say, a super black pastel that shows no issues at all, from parents that also show no issues at all, you will get offspring that also shows no issues. or am i wrong and even in this case, in offspring that contains only one copy, the issues still randomly pop up?

should the single-gene morphs be added to the list of morphs with inherent genetic problems? should all people that do not want to deal with any genetic issues remove these genes from their collections, even if the examples they have so far are flawless? i have a hard time believing that its as bad as you make it sound.

But I can answer, Duck billing might be a polygenetic trait and black pastel/cinny is just one of the main parts to make it show, but the normal allele resists it pretty well or it might have something to do with epigenetics. Both would suggest that breeding animals without problems would tend to have babies without problems, but depending on how the trait works, one wrong event could make the unwanted trait show up. Chances are it is not random but complex in some way. I mean hundreds of people have zero issues, but satomi325's friend hatched a few from the same stock of animals (im assuming), so I think they just unknowingly had the conditions to make it happen in their stock, whatever that might be.
