Sorry but when I read my post I noticed a couple of errors... and unfortunatly ran past the editing time allowed so here is a repost with corrections...
THe sire is Black, but his dad was a black Roan and his mom was a Sorrel. The mare is champagne (not sure which one). Her dad is a champagne but darker and I have no idea what her mom was but I am guessing she had champagne too because of the mare's coloring. What options should I put in on that color predictor website?
Stallion - Ee aa this is a black who is also able to produce the red gene. We know this because his dam was a sorrel. She could only throw ee. Because the stallion is black we know the agouti gene is aa (non agouti).
Now is the hard part. Assuming the mare is an Amber Champange with or without cream gene you know you are going to have a bay base. This will give you at least one E and one A. You also know you have at least one Ch gene.
So far you are strongest for Bay or Amber Champange - Ee Aa or EE (homozygous black) Aa.
Next is the black or Classic Champange which is black based - Ee aa or EE aa. This is assuming the mare is not AA.
Finally the chestnut or the Gold Champange which is chestnut based - ee Aa or ee AA. This is assuming the mare is not EE.
Either AA or EE will eliminate the possiblity of black or chestnut, in that order... both EE and AA will mean all you get is bay.
The Ch or champange gene will modify the base color which is black, bay, or chestnut. Same with the creme gene.
If the creme gene is available this makes it more fun. With a bay base you'll have buckskin, black is smokey black and chestnut creates palomino.
And if there is a silver gene...
So in reality.... without knowing the homozyogous of the champagne or if there is a creme gene homozygous or not...
You are guaranteed to have just about anything.
If you have the extra cash I recommend getting the champange and creme gene tested. I have all my broodmares tested to help my breeding decisions. Or you can just wait and see what arrives. Like my latest. I knew for certian the foal would be bay but only had a 50/50 chance for Appy marking... and I got them!!
