* Unlike the Cream gene, the Dun, Roan, and Champagne dilution genes are simple dominant and do not
affect the coat color differently when the horse carries one or two of the genes.  As you can see from above, the
Cream gene will modify the color of the horse depending on whether the horse carries one or two copies of it.

An upper case "E" represents the BLACK gene. A lower case "e"
would mean the horse carries a RED gene instead of black. One upper
case "E" will result in a black based foal.  The next gene, agouti, will
determine if the foal remains black based or will be bay based.

"A" is represents the Agouti gene.  This gene restricts a BLACK base to
just the points.  This gene does not affect a red based coat color.  
Lower case "a" would mean the horse would not have the dominant
agouti gene.

For breeders looking to get BLACK foals, breeding a mare that is "AA"
for Agouti will NEVER result in a black foal. This is another reason to
know the genetics of the parents before trying to produce a particular
foal. Also, a foal receives one copy from each parent, so an "EE" horse
will always give a black base to its offspring. An EE parent will never
produce a foal color in the top row of the chart to the right. Likewise, an
"AA" parent will never produce a foal in the bottom row of the chart.
