Breeze Web,

You have touched on one of my favorite subjects. I love genetics. There are a lot of unknowns. But by looking at the stallion, and the mare with no DNA posted here is what I came up with.

Putting the stallion For each of the following combonations as:
CrCr for the cream
Aa Hetrozygous for Agouti (Since he has buckskins in his lineage)

Not knowing exactly what the mare is for sure, sometimes they surprise you here are a couple options.

#1 Mare as Red gene Hetrozygous Ee
Agouti hetrozygous Aa
Roan factor Hetrozygous Rr = 25% palomino Roan, 25% palomino, 18.75% either buckskin roan or buckskin, 6.25% smokey blue roan, and 6.25% smokey black

#2 mare as hetrozygous red Ee
homozygous agouti AA
Hetrozygous roan Rr = 25% of one of the following palomino roan, palomino, buckskin roan or buckskin

#3 Mare as Homozygous red EE
homozygous agouti AA
homozygous roan RR = 50% chance of Palomino roan or 50% buckskin roan

#4 mare as Homozygous for red EE, and Hetrozygous for agouti Aa and roan Rr
= 50% buckskin roan or 50% Buckskin

#5 mare as homozygous for red EE, agouti AA, and roan RR= 100% buckskin roan

These options are just that, without knowing exactly what each horse is it is hard. And not knowing the exacts one your mare if she is really a bay roan or a red roan....

Not matter what is bred to that stallion it will come out as some dilution because he carries the double cream gene.

Hope this helps, have fun.
