Has anyone thought that maybe all morphs are allelic? That there are hundreds of different allele working in a dominance series of multiple alleles? Possibly even Pleiotropic and Epistasis Alleles? Could even be Polygenic? Just a thought.
I'm looking for as simple an explanation as possible for what I'll get when I breed A to B and will leave the pondering of these deeper genetic questions to those whose fancy they tickle.
