Phenotypes of A-/E- Gene Combinations

This chart was a collaboration between myself and Laura Lyon. B-C-D- are assumed for the other genes.

Black with possible alternating patches of ticking. ***Black with some possible ticking, that can come and go. Black. Some ticking could be possible.

**A knowledgeable Steel ND breeder contends that steels appearing brighter/more "chestnut" [or tweeners] are due to the effects of modifiers and being AAEsE. He believes a AaEsE provides a more moderate amount of ticking and darkens the bottom of the tail.
*** SOME commercial breeds seem to have modifiers that allow this genotype to appear as a properly expressed Steel. It does not seem to be the case with the Fancy breeds.
