I'd really like to know if she can throw a black foal and what those chances are. I'm using http://www.horsetesting.com/CCalculator2.asp to calculate those chances, but I really need to figure out Agouti genes, which I'm trying to do through looking at her sire and dam. Here's what I got so far:
Her Sire is a buckskin dun, with parents that were another buckskin dun and a chestnut. From this I can deduce that his genes were heterozygous for the Agouti gene, and therefore she could carry either the dominant or recessive version from him. (I used Mountain View Farm - What color will I get? to figure that out).
I have no idea what color her dam is. If anyone who has access to the AHA database can help me out with that, I'd really appreciate it. Of course, if no one does, the lady who's selling her will probably know the dam's color. In that case, if you can tell me any information for what I can expect from different colors, I'd appreciate that as well. Thanks so much!
