I have always been fascinated by colour genetics. There has always been one aspect however that my mind has stumbled over, perhaps someone can clarify for me...
It is the definition of a bay vs. the definition of a brown and where you draw the line between the two? I know some geneticists consider brown to be a type of bay. I tend to feel that the seal browns are separate from bay, but that some "brown" horses with black points are just shades of bay. What do you think?
Also does the agouti series influence chestnut colour? I know that chestnut horses carry agouti and in one of my books it says that the shades of chestnut are caused by agouti, ie. liver, standard orange/brown, red, and sandy chestnut. Has anyone else heard/read this?
