Hmmm. Alright, I'll try that. Thanks!

I'd first try just removing one PATN1. It can remove enough to make some visible, and he'd still be hom appy. If that doesn't work like you want, I'd then remove an appy. Since brindle may not show well on a het appy, hom PATN1 horse. That's what I'd do.

@WindSongStables She cannot GMT the mare, since it has been bred and there is a foal. But she can GMT the foal to change what was inherited from the dam. When you look at the genes, the first allele of a gene is what was inherited from the sire, and the second allele is what was inherited from the dam. So the dam was only heterozygous for the appy (Lp) gene, meaning only half of the time will the mare pass on the Appy gene. So to achieve the desired look, you can remove the inherited Appy gene from the dams side of the allele to get an Appaloosa that actually shows the spots. Then, since the sire is only heterozygous for the PATN1, meaning he will not have a full body blanket of spots, the inherited copy can be removed from the foal to create a smaller blanket and allow some of the brindle markings to show.

Yay! I’m so happy it worked for you, he’s handsome
