Ok so I need someone to confirm my thinking because the stud my friend bred her mare to can't be cremello right lol? Basically he is supposed to be cremello and the owner of the stud said both the stud's parents are palomino so he should be a typical cremello in theory. But he sired a buckskin with a chestnut mare and that can't be possible unless he carries a black gene correct? I'm fairly certain he is homozygous agouti since all the mares he's been bred to besides sorrels have been buckskin and when bred to chestnut mare's they have been palomino besides the odd bucksin that popped out.
So basically I'm asking if he had a buckskin with a sorrel mare he HAS to be be Perlino. I have pictures of the stud and the buckskin colt but I do not own the pictures so I will PM you the pics if you would like to see them since I do not want to post pictures without permission.
