Thanks for your comments, Maurice.
I’m a very small-scale casual hybridizer and plan to cross an extra-large-sized bloom that has heavy ruffles with a smaller bloom that has lots of big teeth. Would like to get a large to extra-large-sized bloom with teeth and my suspicion is that I will have a fairly high likelihood of success.
One might be able to loosely use the term “dominant” to describe teeth because it seems to be true more often than not that teeth get passed on and are visibly displayed by children. However there are of course many variables that could come into play on any specific cross. My ruffled bloom could cause some gene interaction that eliminates the teeth. I’ll have to wait and see!
I'm going to cross teeth with a pie-crust edge and that will be interesting as well...
