This mare has tested as Ee aa Dd which means that she is black based, has no bay/brown agouti and has dun (which makes her a grulla). The appaloosa genes have caused her base coat to appear as something it is not. This is the hazard with trying to guesstimate base coats on appaloosa patterned horses without knowing for sure what colors are also in their back ground.
Pretty mare!! Appaloosa coloring has always stumped me.
I will most definitely by getting her tested! I didn't realize it was quite so easy! Wish I woulda thought about it sooner, I JUST pulled and quartered her mane and threw away all the loose hairs.
Thank you NdAppy for the links!
Don't send in dead or loose hair. Pull from the root, one hair at a time so each has part of the root on it. Pull about 20. Place in a plastic bag and label the bag with tape, with your name on it and the name of the horse. Then send it in to the testing place of your choice.
